New cards

what are two types of carbonyls

aldehydes and ketones

2
New cards

what is the most common reaction for carbonyls to undergo

nucleophilic addition

3
New cards

process of nucleophilic addition

the carbonyl group in aldehydes and ketones is polarised. the oxygen atom is more electronegative than carbon, drawing electron density towards itself. this leaves the carbon slightly positive and the oxygen slightly negative. the carbon compound is therefore susceptible to attack by a nucleophile.
