`CH_(3)CHO` and `C_(6)H_(5)CH_(2)CHO` can be distiguished chemically by

A

Benedict's test

B

Iodoform test

C

Tollens' reagent test

D

Fehling's solution test

Text Solution

Verified by Experts

The correct Answer is:
B
Acealdehyde contains the `CH_(3)CO-` group attached to H and hence gives iodoform test but `C_(6)H_(5)CH_(2)CHO` does not.
