Benzaldehyde and acetone can be best distinguished using

Options

AFehling's solution
BSodium hydroxide solution
C2, 4-DNP
DTollen's reagent

Correct answer

D. Tollen's reagent

Step-by-step solution

With Fehling's solution, benzaldehyde as well as acetone do not react while with Tollen's reagent, benzaldehyde gives precipitate but acetone does not react. Hence, Tollen's reagent is used to distinguish them.
