Question -
Answer -
On vigorous oxidation, it gives 1, 2-benzenedicarboxylic acid. Identify the compound.
Answer
It is given that the compound (withmolecular formula C9H10O) forms 2, 4-DNP derivative and reduces Tollen’s reagent.Therefore, the given compound must be an aldehyde.
Again, the compound undergoes cannizzaro reaction and onoxidation gives 1, 2-benzenedicarboxylic acid. Therefore, the −CHO group is directlyattached to a benzene ring and this benzaldehyde is ortho-substituted. Hence,the compound is 2-ethylbenzaldehyde.
The given reactions can be explained by the followingequations.
