To the Student<br >Right now， confronted with the array of unfamiliar material in your textbook， you must be<br >wondering: what am I expected to get out of all this ?<br > The best way to find out is to work problems: first， to see if you understand the facts<br >and principles you have been reading about; second， and more important， to learn how to<br >use this chemistry in the same practical ways that an organic chemist does.<br > Give yourself a fair chance to work each problem. Don t give up too easily. Re-read<br >the pertinent part of the text. Think about it. Use paper and pencil and really work at it.<br > Only after you have done all that， check your answer against the one in this Study<br >Guide. If you were on the right track， fine. If you went off the track， try to see where.<br >Follow through the explanation carefully to see how you should approach this kind of<br >problem next time<br > You must learn how to use your brand-new organic chemistry， and to do this you<br >must push yourself. You must try to work difficult problems， and you will not always<br >succeed. But you can learn from your failures as well as your successes.<br > With some answers， we have given references to the chemical literature. It is not<br >necessary for you to read all of these papers--or even any of them. But if some topic<br >catches your fancy， follow it up. And， in any case， read one--or two or three--of these<br >papers， so that you can see in down-to-earth detail the kind of experimental work that<br >underlies any science.<br > Robert Thornton Morrison<br > Robert Neilson Boyd<br >
