Question

toluene undergoes oxidation to give?​

Answer 1

Answer:

undergoes sulfonation to give p-toluenesulfonic acid, and chlorination by Cl2 in the presence of FeCl3 to give ortho and para isomers of chlorotoluene. Importantly, the methyl side chain in toluene is susceptible to oxidation. ... The methyl group undergoes halogenation under free radical conditions.

Explanation:

The routes involved in toluene oxidation have been delineated: toluene oxidation proceeds via the formation of benzyl , by H-atom abstraction, and the formation of benzene , by H-atom displacement yielding methyl and benzene ; benzyl oxidation yields benzaldehyde , that further reacts yielding phenyl whereas benzyl .

The most characteristic product of toluene oxidation is ben- zaldehyde. It was noted that, when the reaction was per- formed on usual oxide “mild” oxidation catalysts, it ter- minated at the stage of benzaldehyde formation, whereas benzoic acid was present in oxidation products in insignificant amounts
