You have finally gotten to the first of several chapters that examine the chemistry of carbonyl compounds: the most important ones in organic chemistry. Why are they so important? They are extremely ver￾satile in carbon–carbon bond formation, and, therefore, synthesis. Carbonyl compounds contain an electrophilic carbonyl carbon (which you already know about from Chapter 8) as well as a potentially nucleophilic carbon next to it (which you will learn about shortly). This “double-barreled” functional capability is unique among the simple compound classes. The importance of carbonyl compounds extends to biological chemistry as well, where the carbonyl group plays a central role in biochemical synthesis of naturally occurring molecules.

Naming the Aldehydes and Ketones Most of the material in these sections is of a relatively routine nature, so only a few points of special interest, or with special implications, will be mentioned. 304 1559T_ch17_304-322 11/3/05 10:48 Page 304
