Vedclass · Answer

(B) The reaction of acetaldehyde with sodium bisulphite $(NaHSO_3)$ is a classic example of a nucleophilic addition reaction. In this reaction,the bisulphite ion $(HSO_3^-)$ acts as a nucleophile and attacks the electrophilic carbonyl carbon of the acetaldehyde to form a crystalline bisulphite addition compound. This reaction is reversible and is commonly used for the purification and separation of aldehydes and ketones.
