Contents of three bottles were found to react
(i) Neither with Fehling's solution nor with Tollens reagent
(ii) Only with Tollens reagent but not with Fehling's solution
(iii) With both Tollens and Fehling's solution. If they contained ethanal (acetaldehyde) or propanone (acetone) or benzal (benzaldehyde), which bottle contained which

Options

A. In (i) benzal, in (ii) ethanal and in (iii) propanone
B. In (i) benzal, in (ii) propanone and in (iii) ethanal
C. In (i) propanone, in (ii) benzal and in (iii) ethanal
D. In (i) propanone, in (ii) ethanal and in (iii) benzal

Answer

C

Explanation

Propanone does not react with Fehling’s solution and Tollen’s reagent.
Benzaldehyde does not react with Fehling’s solution but reacts with Tollen’s reagent. Ethanal reacts with both.
