Vedclass · Answer

(A) Aromatic carboxylic acids can be prepared from alkyl benzenes by vigorous oxidation of the alkyl side chain using strong oxidizing agents.Alkaline potassium permanganate $(KMnO_4/OH^-)$ and chromic acid $(H_2CrO_4)$ are well-known strong oxidizing agents used for this purpose.Dilute nitric acid $(HNO_3)$ is also capable of oxidizing the alkyl side chain of alkyl benzenes to a carboxylic acid group.Diborane $(B_2H_6)$ is a reducing agent,typically used for hydroboration-oxidation reactions to convert alkenes into alcohols,and it is not used for the oxidation of alkyl benzenes to carboxylic acids.Therefore,the correct answer is $A$.

Which among the following compounds is $NOT$ used for the preparation of aromatic carboxylic acids from alkyl benzene?
