Text Solution

Verified by Experts

The correct Answer is:
B
must contain `(MeCO-)` group to give iodoform test. The reaction `(C )` to `CH_(3)COOH` shows that `(C )` must be `beta`-keto acid because on heating it easily undergoes decarboxylation, (or) `(C )` must be a dibasic acid. On heating it also loses `CO_(2)`. Therefore, `(C )` must be a dibasic acid beacuse after iodoform reaction, `(A)` is converted to sodium salt of acid. So the answer is `(b)`.
