Question

How do you account for the following observations ? (3)

(a) Though alkaline potassium permanganate and acidic potassium

permanganate both are used as oxidants, yet in the

manufacture of benzoic acid from toluene we use alcoholic

potassium permanganate as an oxidant. Why? Write a balanced

redox equation for the reaction.

(b) When concentrated sulphuric acid is added to an inorganic

mixture containing chloride, we get colourless pungent smelling

gas HCI, but if the mixture contains bromide then we get red

vapour of bromine. Why? Write the balanced chemical

equation.​
