Q47 / 180 · KCET 2010 · Chemistry

Benzaldehyde and acetone can be best distinguished using

A
Fehling's solution
B
Sodium hydroxide solution
C
2, 4-DNP
Correct answer
D
Tollen's reagent

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.

Hence, the correct answer is option: 'D'.
