A

Fehling's solution

B

Sodium hydroxide solution

C

2,4-DNP

D

Text Solution

Verified by Experts

The correct Answer is:
D
Benzaldehyde is a weak reducing agent. It reduces ammoniacal silver nitrate solution to give silver mirror.
`C_(6)H_(5)CHO + Ag_(2)O rarr 2Ag darr + C_(6)H_(5)COOH`
Acetone is not easily oxidised & hence, does not give the Tollen's test.
