LECTURE Chapter 17: Aldehydes and Ketones Now that we have covered electrophilic aromatic substitutions and cyclic structures, we will move on to aldehydes and ketones, the topic of chapter 17. The functional group in particular that we will look at is the carbonyl, C=O. An aldehyde has a structure of RCHO, whereas a ketone has a structure of RCOR. Nomenclature The carbonyl group of aldehydes and ketones has priority over all other polar or functional groups used so far, namely RX, ROH, alkenes, alkynes, and phenyl groups, but not COOH. In addition, aldehydes have priorities over ketones. For aldehydes, IUPAC naming converts an alkane to an alkanal. The longest chain starts at the carbonyl carbon, which is C1....
