An organic compound of M.F. `C_(8)H_(8)O` forms 2, 4-DNP derivative, reduces. Tollens reagent and undergoes Cannizzaro reaction. On vigorous oxidation it gives Benzene-1, 2-dicarboxylic acid. The compound is

A

2-ethylbenzaldehyde

B

2-methylbenzaldehyde

C

acetophenone

D

3-methylbenzaldehyde

Text Solution

Verified by Experts

The correct Answer is:
B
Since, the compound forms 2, 4-DNP derivative, so it must be a carbonyl compound. It reduces tollen.s Reagent and undergoes Cannizzaro reaction, so it must contain a - CHO group and no `alpha-H` atoms.
Thus, its possible formula may be `CH_(3) C_(6)H_(4) CHO.` Since, it gives 1, 2-benzene-dicarboxylic acid when subjected to oxidatin, so `-CH_(3)` and - CHO groups must be present at successive positions. Thus, the structure of the compound must be
