Q.3 The elevation of boiling point and depression of freezing point of a certain solution of a monobasic acid HA in benzene are AT, and AT, respectively. HA exists usually as a monomer, but it dissociates into ions (with degree of dissociation a) at the boiling point T, of the solution, whereas at the freezing point T of the solution, HA exists as (HA)n with a fixed value of n. The molal boiling point elevation constant and molal freezing point depression constant are K, and Kf, respectively. The correct expression for n is X 1. Ans n = [AT, K; (1+a)] / (AT; K, ) X 2. = [AT, K, (1+a)] / (AT; K; ) 3. (AT, K; ) / [AT, K, (1+a)] X4. (AT, K, ) / [AT, K; (1+a)]
