An organic compound with the molecular formula `C_(9)H_(10)O` forms 2,4-DNP derivative, reduces Tollens’ reagent and undergoes Cannizzaro reaction. On vigorous oxidation, it gives 1,2-benzenedicarboxylic acid. Identify the compound.

Explanation

`to` The compound having molecular formula `C_(9)H_(10)o` forms a2,4-DNP derivative and reduces Tollen's reagent . So its is an aldehyde.
`to` it undergoes cannizaro reaction, so the aldehyde group should be directly attached to the benezene ring.
`to` On vigorous oxidation , it gives 1,2 -benzene dicarboxylic acid, so it should be an ortho substituted benzaldehyde . For molecular formula `C_(9)H_(10)O`, the possibility is only O-ethyl benzaldehyde.
`to` The equation for all reactions are given below.
