Tollen's reagent and Fehling solutions are used to distinguish between

A
acids and alcohols
B
alkanes and alcohols
Correct answer
C
ketones and aldehydes
D
n-alkaens and branched alkanes

Solution

All aldehydes and ketones show reaction with Tollen's reagent and Fehling solutions, but ketones do not show this reaction. Note :- Benzaldehyde do not give reaction with Fehling solution.

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