Answer» Solution :The reaction in acid medium : `MnO_(4)^(-)(aq)+BH^(+)(aq)+5etoMn^(2+)(aq)+4H_(2)O(l)` Multiplying equation (1) by (6) and equation (2) by 5 and then adding them together ,we have The reaction in alkaline or neutral medium : Multiply equation (3) by (2) and then adding it to equation (4) ,we have, Even through toluence oxidises to benxoic acid in pressence of ACIDIC or alkaline `KMnO_(4)` the manufacture of benzonic add from toluene is usually carried out by using alcoholic `KMnO_(4)`as an oxidant This is because of the following advantages: (i) The USE of alcoholic `KMnO_(4)` is cost effective because to carry out the reaction in pressence of its does not requie adding of either acid or alkali in the reaction medium .In a neutral medium `OH^(-)` ions are produced during the reaction . |
