Question

Is addition of sodium bisulphite to aldehydes a base catalyzed reaction?​

Answer 1

Answer:

$\underline{\huge{Answer:-}}$

Aldehydes react with sodium bisulphite (sodium hydrogen sulphite) to give addition products. Ketones, except for methyl ketones, do not react with sodium bisulphite due to steric hinderance (crowding).

Answer 2

Answer:

The addition of sodium bisulphite to carbonyl compounds. The reaction follows the mechanism as for base catalyzed Nucleophilic addition. This mechanism suits all aldehydes and ketones with lower chains (methyl) atleast on a single side.
