Question

An organic compound with the molecular formula C7H6O forms
2,4-DNP derivative, reduces Tollen's reagent and undergoes
Cannizzaro reaction. On oxidation, it gives benzoic acid. Identify
the compound and state the reactions involved.​

Answer 1

Answer:

pls mark me brilliant and follow me

Explanation:

Again, the compound undergoes cannizzaro reaction and on oxidation gives 1, 2-benzenedicarboxylic acid. Therefore, the -CHO group is directly attached to a benzene ring and this benzaldehyde is ortho-substituted. Hence, the compound is 2-ethylbenzaldehyde.
