Question

Why aromatic aldehyde doesnot form silver mirror in tollens test?

Answer 1

Answer:

Explanation:

Fehling's solution (comparatively a weaker oxidizing agent than Tollen's reagent) can't oxidize benzaldehyde (an aromatic aldehyde). However, Fehling's solution can oxidize an aliphatic aldehyde. bond in the carbonyl group is reduced because the C−H bond now has a higher electron density.
