Explanation

P) Hydrazine (N2H4) is a nitrogen hydride. In Raschig process it is prepared by the reaction of ammonia with sodium hypochlorite in dilute aqueous solution. Q) Borazine, B3N3H6 known as inorganic benzene in view of its ring structure with alternate BH and NH groups. R) Boric acid is a weak monobasic acid. It is not a protonic acid but acts as a Lewis acid by accepting electrons from a hydroxyl ion. Hence, statements P and R are false.
