Which one of the following does not form sodium bisulphite addition product with sodium bisulphite solution

A.CH2O
B.C6H5COCH3✓ Correct
C.C6H5CHO
D.CH3CHO
Explanation

All aldehydes (aliphatic and aromatic) can react with sodium bisulphite and will give addition products. In ketones only methyl ketones react with sodium sulphite to form addition products. So, from the given options, acetophenone has bulkier groups on the carbonyl group, hence it will not react with sodium bisulfite
