Summary

Chapter 17: Aldehydes and Ketones. Nucleophilic Addition to C=O

 

Aldehydes (RCHO) and ketones (RCOR') are very important functional groups, characterized by the presence of an acyl group (C=O) bonded either to H (aldehydes) or another C (ketones).
There are two contrasting, but equally important reactivity patterns for these compounds:

1.  Aldehydes and ketones are attacked by nucleophiles due to the electrophilic character of the carbonyl C. (Chapter 17) 
carbonyl resonance
2.  Treatment of aldehydes and ketones with a suitable base can lead to the formation of a nucleophilic species called an enolate that reacts with electrophiles. (Chapter 18) preparation of an enolate

In this chapter, we will be looking at the reactions of aldehydes and ketones with nucleophiles:
