An organic compound (A) on treatment wit...

An organic compound `(A)` on treatment with ethyl alcohol gives a carboxylic acid `(B)` and compound `( C)`. The hydrolysis of `( C)` under acidic conditions gives `(B)` and `(D)`. Oxidation of `(D)` with `KMnO_4` also gives `(B)`. `(B)` on heating with `Ca(OH)_2` gives `(E)` (molecular formula, `C_3 H_6 O`). `(E)` does not give Tollens test and does not reduce Fehling's solution but forms a `2,4-`dinitrophenyl hydrazone. Identify `(A),(B), ( C), (D)`, and `(E)`.

A

an ester

B

an alcohol

C

a carboxylic acid

D

an acid anhydride.

Text Solution

Verified by Experts

The correct Answer is:
D
The compound [A] is an acid anhydride as it reacts with ethyl alcohol to form carboxylic acid ester [C].

An organic compound ‘A’ on treatment with ethyl alcohol gives a carboxylic acid ‘B’ and compound ‘C’. Hydrolysis of ‘C’ under acidic conditions gives ‘B’ and ‘D'. Oxidation of ‘D’ with KMnO_4 also gives ‘B’. ‘B’ on heating with Ca(OH)_2 gives ‘E’ (molecular formula, C_3H_6O ). ‘E’ does not give Tollent’s test and does not reduce Fehling’s solution but forms a 2,4- dinitrophenylhydrazone. The compound ’E' is:
