In carbonyl compounds, the carbonyl group is polar as well as in `sp^(2)` hybridisation state. As a result, these compounds are highly reactive in nature and take part in the addition reactions. The mechanism of these reactions is nucleophilic in nature and is catalyseed in the weakly acidic medium. The extent of nycleophilic addition is influenced by two factors. These are steric effect of the groups attached to the carbonyl carbon atom. Both tend to decrease the reactivity of these compounds in the nuclephilic addition reactions.
Which of the following statements regarding carbonyl compounds is not correct?

A

The addition reactions occurring across the `gtC = O` bond are of electrophilic type.

B

The addition reactions occurring across the `gtC=O` bond are of nucleophilic type.

C

Aldehydes undergo addition reactions more readily than ketones.

D

The addition reactions shown by `gtC = O` group are catalysed by acids.

Text Solution

Verified by Experts

The correct Answer is:
