Name the reagent used in the following reactions: C_(6)H_(6)-CH_(2)-CH_(3) overset(?)to C_(6)H_(5)-COO^(-)K^(+)

Answer»

Solution :When an alkylbenzene is heated with `KMnO_(4)-KOH`, the entire side CHAIN is oxidised to `COO^(-)K^(+)` irrespective of the length of alkyl side chain.
`UNDERSET("Ethyl BENZENE")(C_(6)H_(5)-CH_(2)-CH_(3)) underset(Delta)OVERSET(KMnO_(4)-KOH)to underset("Pot. benzoate")(C_(6)H_(5)-COO^(-)K^(+))`
