Without this skill it will be impossible to master even the most basic reactions and concepts. Molecules can be drawn in many ways. For example below are three different ways of drawing the same molecule: Without a doubt the last structure bond-line drawing is the quickest to draw the quickest to read and the best way to communicate. Lines are drawn in a zigzag format where each corner or endpoint represents a carbon atom.
For example the following compound has 7 carbon atoms: It is a common mistake to forget that the ends of lines represent carbon atoms as well. The two carbon atoms of the triple bond and the two carbons connected to them are drawn in a straight line. Most hydrogen atoms are not shown so bond-line drawings can be drawn very quickly. Hydrogen atoms con- nected to atoms other carbon such as nitrogen or oxygen must be drawn: But hydrogen atoms connected to carbon are not drawn.
Here is the rule for deter- mining how many hydrogen atoms there are on each carbon atom: neutral carbon atoms have a total of four bonds. In the following drawing the highlighted carbon atom is showing only two bonds: Therefore it is assumed that there are two more bonds to hydrogen atoms to give a total of four bonds. This is what allows us to avoid drawing the hydrogen atoms and to save so much time when drawing molecules.
It is assumed that the average per- son knows how to count to four and therefore is capable of determining the number of hydrogen atoms even though they are not shown. So you only need to count the number of bonds that you can see on a carbon atom and then you know organic chemistry as a second language pdf download there should be enough hydrogen atoms to give a total of four We only see two bonds connected to this carbon atom SH OH N H 1.
OH O slide 7: bonds to the carbon atom. After doing this many times you will get to a point where you do not need to count anymore. Now we will do some exercises that will help you get to that point. Count the num- ber of hydrogen atoms connected to each carbon atom, organic chemistry as a second language pdf download. Of course we save time by not drawing every C and H. Not only are they easier to draw but they are easier to read organic chemistry as a second language pdf download well.
You need to stare at it for a while to see the change that took place. However when we redraw the reaction using bond-line drawings the reaction becomes very easy to read immediately: As soon as you see the reaction you immediately know what is happening. In this reaction we are converting a double bond into a single bond by adding two hydrogen atoms across the double bond.
Once you get comfortable reading these drawings you will be better equipped to see the changes taking place in reactions. Take the following molecule as an example: To draw this as a bond-line drawing we focus on the carbon skeleton making sure to draw any atoms other than C and H.
All atoms other than carbon and hydrogen must be drawn. When you begin learning reactions in your course you will start to encounter synthesis problems in your textbook.
In a multistep synthesis you can often end up with a product that looks very different from the starting material. For example look at the following series of reactions below. Imagine that you are learning how to play chess.
Then you learn how each piece moves and organic chemistry as a second language pdf download they capture each other. Most strategies in- volve thinking more than just one move in advance.
It is not good enough to know only how to move the pieces. Imagine how silly it would be to take the time to learn how to move the pieces but to then say to yourself that you are not good at strategy. That would be silly because that one aspect of the game is the whole game itself. There is no in-between. Organic chemistry is very much the same.
Synthesis is all about strategizing. You need to think a few moves ahead and you must learn how to do this. You organic chemistry as a second language pdf download not tell yourself that you are not good at synthesis problems and therefore you will just focus on the other aspects of organic chemistry.
Synthesis is organic chemistry. The second half of the course is all about learning reactions and applying them in syntheses.
Everything that you have learned so far has prepared you for synthesis. As you learn more and more reactions this list will grow. If you keep up with this exercise as the course progresses you will be in very good shape for solving one-step synthesis problems. The hardest challenge that you will face is keeping up with the work and not waiting until the night before the exam. The secret to success in this course is to do a little bit every night rather than cramming on the night before the exam.
Begin your list on the next page. For now skip forward a few pages. We have some techniques to go over that will help you solve synthesis problems, organic chemistry as a second language pdf download. For each reaction just draw the starting material in front of the arrow and the products after the arrow, organic chemistry as a second language pdf download. Leave the space above the arrow empty.
