Answer :
Two moles of permanganate are required to oxidize one mole of toluene to benzoic acid.
Toluene is oxidized to benzoic acid by using alcoholic potassium permanganate. In neutral medium hydroxide ions are produced. This reduces cost of adding acid or base.
The following reaction shows the result
C6H5CH3 + 2MnO3 = C6H5COO- + 2MnO2 + H2O +OH-
Alcohol and KMnO4 are both polar and homogeneous to each other. Toluene and alcohol are homogeneous as they are organic. Thus, in alcohol the rate of reaction between toluene and KMnO4 is higher.
