An organic compound with the molecular formula C_(8)H_(8)O forms 2,4-D

1.	An organic compound with the molecular formula C_(8)H_(8)O forms 2,4-DNP derivative, reduces Tollens' reagent and undergoes Cannizzaro reaction. On vigorous oxidation, it gives 1,2-benzandicarboxylic acid. The organic compound is
Answer» 2-ethylbenzaldehyde 2-methylbenzaldehyde acetophenone 3-methylbenzaldehyde Solution :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.
