Answer:
Toluene and the derivatives of toluene undergo oxidation with the help of a strong oxidizing agent to form benzoic acids. However, it is possible to stop the reaction at the aldehyde stage with the help of proper reagents. The reagents can convert the methyl group to an intermediate that cannot undergo further oxidation easily. Oxidation of methylbenzene or toluene falls under two categories on the basis of reagents used in the reaction
Use of chromyl chloride
Use of chromic oxide
