Question

The most characteristic reaction of aldehyde and ketones is nucleophilic addition to carbon oxygen double bond. Aldehyde and ketones are easily susceptible to nucleophilic addition because of structural features. The trigonal planar arrangement of groups around the carbonyl carbon atom means that the carbonyl carbon atom is relatively open to attack from above and below the plane of carbonyl group. The partial positive charge on the carbonyl atom means that it is especially susceptible to attack by a nucleophile
