1.	Give reasons for the following : tert-Butylbenzene does not give benzoic acid on oxidation with acidic KMnO_4
Answer» Solution :Alkylbenzenes in which the alkyl groups contain one or more `alpha`-hydrogens or BENZYLIC hydrogens on VIGOROUS oxidation with ACIDIC `KMnO_4` ultimately give the CORRESPONDING benzoic acids irrespective of the length of the CARBON chain. For example, tert-Butylbenzene , on the other hand, does not contain any `alpha`-hydrogen or benzylic hydrogen and hence does not undergo oxidation easily to give benzoic acid
