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

`CH_(2)O`

B

`C_(6)H_(5)COCH_(6)`

C

`C_(6)H_(5)CHO`

D

`CH_(3)CHO`

Text Solution

Verified by Experts

The correct Answer is:
B
Crystalline solid derivatives are formed when aldehydes or ketones are shaken with saturated aqueous solution of sodium bisulphite, but sodium bisulphite, is a bigger nucleophile . So, all ketones do not give this test. Only aliphatic methyl ketones form addition product with sodium bisulphite.
