Anorganic compound with molecular formula `C_9H_10O` forms 2,4-DNP derivative, reduces Tollens' reagent and undergoes Cannizzaro's reaction. On vigorous oxidation it gives a dicarboxylic acid which is used in the preparation of terylene. Identify the organic compound.

Explanation

Since the compound forms 2,4-DNP derivative and reduces Tollens. reagent, it is an aldehyde. It undergoes Cannizzaro.s reaction, therefore, it does not have any a-hydrogen. It gives a dicarboxylic acid, i.e., which is used in the preparation of terylene. This acid is formed on vigorous oxidation of the given organic compound. Therefore, compound should have two side chains. Thus, the aldehyde having formula `C_9H_10O` is
