Compound X is an isomer of nitrotoluene. Oxidation of X with acidic KMnO ₄ gives the strongest acid among its isomers. Reduction of X with Sn / HCl gives the weakest base among its isomers. Identify Compound X.

Step-by-step solution

Isomers of nitrotoluene are o -nitrotoluene, m -nitrotoluene, and p -nitrotoluene. Oxidation of these isomers with acidic KMnO ₄ yields o -nitrobenzoic acid, m -nitrobenzoic acid, and p -nitrobenzoic acid, respectively. Due to the ortho-effect (a combination of steric and electronic factors), ortho-substituted benzoic acids are generally stronger acids than their meta and para isomers. Thus, o -nitrobenzoic acid is the strongest acid among them. Reduction of the isomers with Sn / HCl yields o -toluidine, m -toluidi
