Aldehydes (RCHO) and ketones (RCOR') are very important functional groups, characterised 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. (Chapter18) preparation of an enolate

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