An organic compound with the molecular formula, `C_(8)H_(8)O` forms, 2,4-DNP derivative, reduces Tollens' reagent and udergoes Cnnizzron reaction. On vigorous oxidation it gives 1,2-benzene di-carboxylic acid. The organic compound is :

Options

A. 2-ethylbenzaldehyde
B. 2-methylbenzaldehyde
C. acetophenone
D. 3-methylbenzaldehyde

Answer

B

Explanation

Since the organic compound with M.F. `C_(8)H_(8)O`, forms a 2,4-DNP derivative, reduces tollens' reagent and undergoes cannizzaro reaction, therefore, it must be an aldehyde without `alpha`-hydrogen/s. since on vigorous oxidation, it gives ,2-benzenedicarboxylic acid, therefore, aldehyde must be an o-substituted benzaldehyde. further, since benzaldehyde 7 carbon atoms and the given compound contains 8 carbon atoms, therefore, benzaldehyde has a `CH_(3)` group at o-position, i.e., 2-methylbenzaldehyde.
