chemdraw化学式怎么排列整齐

hello， everybody， my name is pierre and this is my advanced kendra video tutorial that is intended for everybody using this software who would like a way to draw molecules a little bit faster to show you what i'm talking about and what you actually can do with kendra as an introduction i am going to draw viagra under twenty seconds so you're probably wondering how i'm doing this while that is the point of this video and i will cover that very soon and we're almost down here and that will be less than twenty seconds now so to be fair i could have also done this under five seconds as i happen to know the genetic name of viagra is sealed in a field i type select control shift n and i get the structure and this way you can also double check that but i didn't do anything wrong before we get into details i'll start with general shortcuts let's just draw a molecule quickly here this is l syrian so with the market all selected if you double click on a molecule you select the whole molecule and if you hold shift while you move it it moves it straight， horizontally or vertically when you have a molecule selected if you hold control and then drag you will quickly make copies of the same molecule so of course now we can combine both control shift and then drag and you will quickly make a line copies of the same molecule if you hold shift and continue double clicking you will select defined objects and double clicking again on it will deselect them now a small trick for reactions let's say we have a reaction like this and this reaction with reagents and conditions so if you take the marky tool and double click on the arrow you select the entire reaction including what stands above and below the arrow and this way you can quickly copy entire reactions now a couple more shortcuts let's change molecules for this i'm going to go with trip to fan yes， i like amino acids so with the molecule selected if you hold control shift out and then h you flip the molecule horizontally and with the v you do the same vertically note that if you do not hold out only control shift and then h or v you flip them all here but you do not retain this tv your chemistry a convenient feature of this action is that you can flip only a part of a molecule so for this i'm going to introduce another shortcut to the lasso tool when you have the market tool selected if you hold out it switches it to the lasso tool so this way you can conveniently access only part of a molecule selected like so and now if you press ctrl shift out h you flip only a part of the molecule lastly， i'd like to cover the cleanup function and for this i'm going to draw quickly your porefriend scaffold i'll draw a couple of five input drinks here that i connect and if you're wondering how i'm doing this i am simply holding out down while i'm using the solid bond tool and it allows me to get the bone length that i want so now i'm going to select the molecule press， ctrl shift k and in journal i'll have to press it several times to get to something that i'm satisfied with so now we're going to double check the structure as usual i write porf hearing i select press control shift n and i get the structure there you go okay let's not move on to the real thing and that is the hotkeys hotkeys are the reason why i'm able to switch between drawing tools like this without even reaching the toolbar also this is how i can modify bonds and atoms for example by default if you go over a bond and press two you make it a double one if you go over an adam and press o you get an oxygen and press n to get a nitrogen so it's all very intuitive but in practice i'd prefer to have it customized my way and this is what this video is about to customize things you need to find one file named hot keys xml to locate it you have to go to file then preferences then directory's tab and that will give you the pat to several kendra folders and you have to follow the one that ends with kendra items now for windows user you have to be careful about one thing is that program data is a hidden folder by default， so you need to enable show hidden folder options in windows okay， so once you have found that file you go to hotkeys you open with a basic text editor and this is what things look like inside so it's important to know that one given hotkey can have up to three different actions and this is why in this file you have three different sections so the first section here object type equals atom is where we're going to find all the shortcuts that apply to single atom in camdrow in the second section object type equals bond is where we're going to find all the shortcuts that apply to bonds and the last section the generic section is where we're going to introduce shortcuts to quickly access drawing tools so to show you how to customize things yourself i'm going to fully customize one hot key that i don't use and that is the hot key u so first i'm going to go to the first section and just copy paste one line like here and now i'm going to change the hotkey value to you the command is label takes so it modifies an atom and i'm going to change it to see you so now when i will go over an atom and press u it will label it with a copper to show you that things are case sensitive i'm also going to introduce another hotkey capital u， that will label an atom with let's say the word awesome don't worry about the description what is written inside the description part has absolutely no impact on the hotkey or the shortcut itself now we're going to go to the bond section and here i'm going to copy paste again one line like so and i'm gonna assign the hotkey u the command is bond order and i'm gonna give it the value force so now when i will press u over a bond it will transform it into a credible bond so now i'm gonna go over the last section and i'm gonna introduce well， you can see that i have already quite a few things customized myself so i'm gonna copy paste one line and i'm gonna introduce the hotkey you as a generic action it will select the tlc plate tool so the command is tool mode and the value here now is tlc plates and i will show you the different commands a bit later so now we're done i'm going to close and yes， i want to save the changes so now we're gonna check that everything worked properly i'm gonna draw a couple bones like this now i will go over this atom and press u and then i get a copper over this one i press capital u and i get the word awesome if i go over this bun and press u i get a quadruple bund and now over nothing i press u and then i get the tlc plate tool and you're welcome important note before you start playing with that file and suggest you make a copy as a backup so here copy paste and be original and emit backup so rule number one if you change the syntax of the hotkeys file none of the shortcuts you've made will be accessible so for example the hotkeys backup file that i just created will not be recognized by kim joe anymore rule number two customize your keyboard one key at a time and make one change close safe and make sure that it's working as you want also stick to letters and figures no symbols or punctuation among all the commands available in kendra， there is the sprout command that i find to be the most useful one and yet not many people know about it so by default if you position yourself over in adam and press zero you sprant one bond if you press nine， you sprant two and if you press eight you sprant three but then of course i have it customized a different way the very nice feature of this command is that it works when you have other drawing tools selected for example i have the bentin ring tool and i can just sprout one bon here and then a couple others like this without changing the tool and this way i draw a trital group very quickly another very interesting feature of this command is that it applies to the last active atom meaning the last atom that was either generated or touched with the cursor for example i can quickly generate an out yell chain by positioning myself over this adam moving away and then pressing repeatedly the hot key corresponding to sprout one bond same here and the same here additionally you can label adam and continue spreading bonds for example i spread a couple once i introduce an oxygen， a couple more more oxygen and then i want to end dimethel so i'm going to introduce a nitrogen and then press sprout two bonds and then of course i can continue， but i have to be careful about one thing is not too type two different characters too quickly one after the other otherwise the software will assume like here that you're trying to type something and the text tool will come up it may also happen that the bonds you're generating with the sprout command close into a six member drink and i don't have an answer as to why it happens sometimes yes， sometimes not but my advice is assign a hot key to the asyclic chain tool like this and when you have an al gail chain to draw then just use that tool and also by the way when you have this asyclet chain tool selected if you hold ctrl， while you move it it follows the movement of the mouse you also have the possibility to quickly generate fused ring systems by positioning yourself over a bond and press five six seven or eight and by default if you position yourself over a bond and press zero you get a chair cycle hexane now one crucial detail is if the last cycle tool that you used was non aromatic then all the rings that will be generated will be saturated if the last cycle tool that you used was aromatic then everything you will generate will be unsaturated like this if you would like to customize these yourself then the command for that is fuse ring and it's present by default on pc versions of kendra， but not on mac where you have to input it manually in the hotkeys file and it may not work on early versions of kendra， if you're in interested here is my personal setup for kendra， and i have described things for aquarity keyboards i'm only giving the shortcuts that i use most often so you should feel free to use it as a starting point and customize it for your specific needs since we all do different kinds of chemistries if you want to customize the hotkeys with during tools i have written below here all the commands responding to each tool and i guess there are self explanatory remember they have to be placed in the third section of the hotkeys file and written in capital letters so in the last section i will go over another very useful feature of camdroh and that is the nickname i will demonstrate how useful nickname can be by drawing taxel here under five seconds there you go so of course the point here is that i drew taxole myself beforehand， but i only drew it once and then i created a nickname for it and now if i need to draw it again i can just type this and and the label you're already using nicknames yourself when you type the name of protecting groups for example the buck group or tvdps here kendra understands which group you are drawing because their structures have been pretty fine to check what they are you can just select the labels individually or a whole molecule and then go to structure like here and expand the label or the shortcut version of this select out s then e， but more than protecting groups you can also define nicknames for large molecule that you may use on a daily basis for example combat seat， attramethel， rotamine or tamara is a commonly used fluorescent group and right now i am just drawing it quickly using all my shortcuts and i will show you how to create a nickname for that and there you go one important thing is when you define the label you need to select the molecule without a connecting bond and this is where the lasso tool becomes really useful remember you hold out with the market tool selected and then select everything accept the connecting bond then you go to structure define nickname and you type what you want in my case tamara be careful it's case sensitive and then you save now again the shortcut version since you may have noticed that i like shortcuts out s then n and then you define the nickname so we just sew a single connection label but you can also create a label with two connecting points and one convenient example of this would be if you use a polyethan like spacer let's just say that you use the backspace area like this one you need to press dot over the atom that you want to define as the first connecting point be careful with the order that you define as it will determine how the label is connected when you draw it later and i define this one as the second connecting point by the way you cannot define more than two connecting points now i take the lasso tool i select then shortcut out s then n and i defined the nickname as peg so now we're gonna make sure that everything worked properly i'm gonna draw lysine the lazy way i type lysine i select control shift n now i draw one bond and i write peg now another bond coming from the peg and tamara， and you will notice that nothing lights up in red and that if ask the molecular weight i actually get a number so let's make sure everything is properly connected i'm going to expand the labels and then some clean up with control shift k and there you go so that's it i hope you've enjoyed this video if you have please spread it around to your friends and colleagues who use kendra， if you'd like to know more about me my name is

使用 camera 绘制青蒿素，首先我们要通过两个六圆环和一个五圆环画出青耗素的基本结构， 但是这边有点没对准，我们需要进行微调，但是这样结构又不好看，所以我们需要对结构进行修正，然后这样就基本结构就 ok 了。然后我们现在需要画出他的所有黑色谢行点， 这边有一个，这边有一个年轻， 这边有一个假机，然后我们需要号召他所有的虚期行件， 这边连了个氧， 这边有个， 然后我们再画出所有单件，单件就这么一个，然后我们现在要补补全所有的氧， 然后我们要画出他的一个双键， 这样清高速的结构就画出来了，但问题是他，嗯，看起来并不是很规则，所以我们需要对他身体结构进行一个修正， 嗯，修建一次，不行就修建两次，这样就看起来， 嗯，非常的规范了。如果我们需要给养生素打上颜色的话，也可以 通过按住 shift 键去选中所有的氧元素，然后不要红，这样就可以了。 如果我们需要加个背景的话，也可以适当加个背景。

今天给大家介绍一下拍不到十四点零左侧的这个工具都是什么意思？上面这两个呢是 选择工具，这个选择工具呢一个是方框的，一个是这种圆圈的，这两个呢有一些区别，这个区别主要在哪呢？在选择的时候，我们比如说要选择下面这整个结构的话呢，我们就选这个方框型的，这样拉一下就好了，这个比较方便。 但是如果说我们只想选择这个结构中的一部分，比如说下面这一部分怎么办呢？我们就必须要选用这种套索型的， 用这种圆圈形的这种套筒工具，然后比如说我们选中之后呢把它颜色改为红色，这样的话呢这个不规则，我们不可能通过拉来选择这一部分，所以说呢这是这两个区别，这个呢是一个立体立体视图，就是 说我们选中了之后呢，我们可以通过推拉，然后呢看他的这个立体的结构，立体的旋转。 下面这个是单件，这个呢就就是说我如果说我们要画单个画眼线的话呢就选这个，然后这个呢是橡皮擦，就是说呢我们想要把某些东西擦掉来选这个就行了，我们可以点点着不不松，然后呢一直划，然后呢我们所有的东西呢都可以划掉， 然后这个呢是化学键、双键、三键粗细键，然后呢要持续键等等呢这些化学键都在这里面，这个呢是一个文本输入的内容，就是说如果说我们想要输入一个文字的集团，比如说输入按键， 我们需要先点击这个，然后呢在合适的地方，比如说这个蓝色光标出现的地方呢，点 a 选一个 a 区二，这个呢就是 可以了。下面这个呢是虚件，这个呢是钢笔工具，钢笔工具，这个呢是也是一个虚的键啊，这个一般用来做这种立体结构的。然后这个呢是箭头，箭头呢有好几种，比如说这种 这种这个双电子的，或者说呢箭头大一点的，小一点的空心的，然后呢弯弯的，这种表示单电子转移的那种鱼钩型的，鱼钩型的箭头包括可逆反应的箭头等等，有很多种类， 这个呢是谢行界去的谢行街，这个呢是轨道，就说 s 轨道、 p 轨道的轨道等等这类的轨道，那轨道的下方呢是各种图形，这个呢大家需要区别区分一下，这个图形里面呢有圆、椭圆，然后呢方框等等，还有这种实心的， 包括这种长直线，长虚线，然后波浪线，还有这种弧形线等等，这个呢是十的线形键，虚的线线线。然后呢这个是波浪舰，波浪舰呢一般表示断剑，对吧？比如说我们这个想要在这断一下，然后我们就选中这波浪舰，哎，在这点一下就好了。 这个这个地方呢就是比如说是括号，有方括号、大括号、小括号等等，好了再往下面呢，这是电子，各种各样的电子符号，表示正电和负电荷，分电子、自由基，双电荷等等， 这个呢是表示对已有的图形的进行进行标注的，这个呢是画表格的 a b 图，比如说呢比如说我们在这画，或者说呢你点击一下，然后他让你写 几行几列，比如说这是二行字列，比如说写三行五列，然后 ok， 然后这个新的表格就出来了， 这个呢是画那个波桑斯湖版的，波桑斯湖版的这个呢是画长的这种链状结构的，比如说我们要画一个正几弯，正几弯，六个碳，对吧？ 六个菜呢？我们这样画的话呢，这个比较慢一些，如果说我们直接选中这个结构，然后直接往右边一拉， 哎，这六个碳已经出来了，这个呢是模板，模板里面呢有很多内容啊，大家看一下这种彩色的这种人体的结构和玩死不要撞，然后氨基酸的侧链氨基酸，还有这种人体结构，小动物，然后方环球环，定环等等，还有常用的这种 实验室的仪器啊，小飞虫，然后各种玻璃仪器，然后各种构像帽环，就是说芳香环，帽环，然后那种大的 放完听电 a， 然后各种关灯团，然后各种各样的，反正这里边呢有各种各样的这种就是 我把大家用的时候呢可以找一下，然后再往下边这一部分呢，就是这三用环、四用环、五用环、六用环、七用环、八用环，包括正九就是缓解完以示勾向，还有这个环环的吸合 比较懂啊，对吧？这是我们常用的这一部分结构内容，这个结这个工具呢，我们就说到这，谢谢大家。

在绘制化学分子结构室，特别是有机分子结构室的时候，你是否经常会碰到某些物质的结构室过于繁琐，绘制起来要花一番时间。那么今天就给大家带来一个快速绘制化学分子结构室的方法， 让你五秒快速绘制出类似这样子的复杂化学分子结构式。我们首先查询想要绘制的化学结构式的 c s 号，比如这里的淀粉复制 c s 号，在菜单栏的 at ins 中选择第二个，在弹出的对话框中粘贴我们刚才复制的 c s 号， 单击 search， 这样淀粉的结构式就出来了，你可以在此结构式基础上进行后续修改。我们再来重试一个，比如这里的枣蓝素，用调等方法进行绘制， 我们同样可以在绘制好的藻蓝素上进行修改。有了这个工具，我们今后再绘制一些复杂化学结构式的时候，可以先从它的母体出发， 找到母体的 c s 号，再在母体的基础上进行修改，这样就会极大提升我们的作图效率。以上就是本期视频的全部内容，我们下期视频再见。

铁啊，别着急，下播之后我会发到群里好吗？你不需要截图，我下播发到群里一个写满答案的一张空白的，我都发到咱们群里边去啊。好，继续增大难度来看氧化铁。 为啥说增大难度了呢？为啥呢？因为刚才大家都在纠结的一个问题是啥？二三题，二三二四六六都齐全。这个铁呀，一会正二一会正三的，到底如何选择？别担心别担心，今天程老教给你，你这辈子再也不忘了啊。这辈子你可能也忘不了程老师了。 好，首先你可能说我不知道是正二还是正三。没问题没问题，先看正甲前副甲后交叉约减定个数。那你看 氧化铁涉及到的元素有什么？有氧元素有铁元素没问题吧？那谁在钱呀？当然是正价钱。好，我管他，铁元素是正二还正三，我不用管他，反正你知。

from the foul menu you can head over to document settings when you get to document settings as we explain in the previous lecture you can first of all start with layout so layout is going to help you adjust how your your wake area is going to look like so you can choose puster and you can also change the display from point to whatever that you need at this point is at this moment is at point so you can choose post that you can choose pages you can change the document size or you can even add the number of pages you can also adjust the margins it doesn't move into the margins so yeah that is quite important and you can also do the pig setup from this point this helps you to see whatever change that you make it helps you to to see how it's going to affect you and your print does if you're printing you can also have headers and footers so you can add a header you can add a text let's say let's call it lol and head okay so you have a header attached to it that can be edited as well， so from the header you can also have a folder and and all that this is the main thing this is where you can change the bond the drawing so you can start with bond you can change the length you can change the width the margins and all so once these things are changed it makes it customized this is why cam draw is important because if you are just using draw or paint or something to do you won't be able to have accurate and you won't be able to have that flexibility and easy ease of drawing right so it makes it very accurate and as we said before some of these geniles wants exact or specific lent and width and specific parameters and can draw gives you that ability to have fixed ones right you can also edit your text so you can let's go back to drawing so there's also angles you have one 20 you can change it as as you need as well yeah you have one 20 from the text you can also have these as your normal text you can also do them here or you can set it so that everything are you do changes then atom labels so when you're labeling atoms it should also be there for you and properties labeling so everything is quiet in here and colors so you can have let's say background color this point is white let's change it to let's say let's go to other you can change it to whatever that you need it to be and hit okay and it changes the background color for you document sentence you can just play around with this as well， so that that is something that can can be done and it's interested so can also change that's from black to let's say red something very useful to do if if you are maybe editing everything in bulk and you can also have custom colors as well， so that is basically it for the interface and we'll be delvin into the basic drawing in the next section so see you？

啊，各位大家好，那么我们在这个 cambo 里面绘图的时候呢，有的时候会遇到这个啊，金属有机配合物 没有的时候呢，需要去进行绘制一个这个呃配位键啊，那比如说我们这随便举了举个例子，比如说这个比定和这个铁配位啊， 那么如果你画一个蛋和铁之间画一个正常的一个单件的话呢，他这个蛋上面就会带一圈这个红色的这个东西啊。嗯，那么画配位键的话呢，我看有些小伙伴他可能直接的话呢，在这里找一个箭头，然后呢从这 哎伸过来打到这，那么这个的话呢，那如果你位置调整好的话呢，呃，身上也看不太出来有什么太大的区别啊，那么实际上，但是这个的话呢，身上 他们是一个孤立的啊，就是相当于是一个片段，就是这个分比例，一个片段，这个箭头一个片段，然后呢这个铁一个片段现在是这样子的，不像这个的话呢，是一个这样子一个整体，那么这样的话呢，这个配配键怎么画呢 啊？在这个多重键里边，你单击这个啊，单击这里的一个小三角啊，那么展开来，那么发现这里有一个 s， 然后呢一个箭头到仰，那么这样的呢，实际上是个配位键 啊，点中他之后呢，我们在这里比如说把鼠标放在这根键上，然后单击鼠标左键啊，那么他就会把这根键变成一个配位键啊，如果你再单击一下他，那么他这个配位键的方向 就会发生变化啊，那么这个可以根据你的需要呢去进行个点击，然后另外的话呢，像这种，那么你可以在这个弹上面，鼠标放在弹上面，然后呢点中之后呢再把它拖到你这个金属上面啊，那么这样子的话呢，也是可以的， 这样的话呢，它就是这个配位键呢就画好了。呃，这个的话呢，就是 camber 里面的这个配位键的一个绘制方法啊，那么希望对大家有所帮助啊，谢谢大家。

啊，各位大家好。呃，那么昨天晚上的话呢，有位小伙伴啊，有位高中老师啊，他问这样子的一个问题啊，就是说这个在 cambo 里面去绘制的时候，怎么让碳这个碳原子连接的这个氢呢？跟在这个碳的这个右后方啊？ 那比如说我们呢在开门教里面啊，比如说我们绘制一个这个环挤完啊，然后比如说我们在这上面输入这个啊， c h r 啊，然后比如说我们在下面这个上下的话，你看绘制出来的话，这个在上面的话，这个琴就会跑到他的上面，在下面的话呢，这个琴会跑到他的下面， 然后呢你比如说在左边啊，在右边，那么琴就是正常的，就是符合他这个要求的，就是说这个呃琴的话呢，是在探的这个右后方啊， 那这个在左边的话呢，他在左边的话，正常的话，我们也就是呃习惯来讲我们也是让他处于这个他的这个轻在这个左边也是也是符合这个要求的。好，那么对于这样子的一个情况的话呢，如果像这样的上下， 还有这个左边的这个，如果你想让他亲在这个右边的话呢，你可以啊，选中这个之后，你看我们选中他之后他会处一个被选中的状态，就是这样一个蓝色的这个方框， 然后呢我们在这个对方对齐这个地方，我们可以选择这个居中啊，那么他就会变成这个清在这个探的呃右侧，然后这个也是一样的。 那那对于这个的话呢，你去进行一个居中，它也可以变成这种形式啊，啊，我们可以把它呢 放大一下啊，好，你看这个样子的话呢，他就全部变成这个啊，碳在左，然后呢琴在右的这样子的一种形式啊，其实就是把把他的一个对齐方式变成这个，就是剧中啊，你也可以试试这个啊，像这个 在这个地方的话呢，你看这个键好像连在青上面的话，你可以把它呢变成一个这个左对齐啊。啊？像这种的话你可以这这个的话还好啊，这个的话你其实没必要去改它，你改成居中的话，它就会变成键好像连在这个碳上面的 啊，这个左对齐就行了，像这个上面下面的这个，嗯，就是一般来说居中对齐就可以了啊，其他的一些集团的话呢，也是类似的啊。呃，就比如说你画一个这种 啊，他也变得很小啊，可能要放大一下啊，比如说你，呃，比如说这个绘制一个 啊，比如说这个服，这种类型的啊，他都是一样的哎，你去对他进行个居中啊，他就会把这个原子呢变成就把这个集团呢变成这样一种形式啊。好，那么希望的话呢，对大家有所帮助啊，谢谢大家。
