Two liquids ‘A’ and ‘B’ form solution which shows significant positive deviation from Raoult’s law. The normal boiling point of pure liquid ‘A’ is higher than that of ‘B’. Which of the following information (s) related with the solution must be incorrect?

Azeotropic mixture of ‘A’ and ‘B’ will have normal boiling point lower than that of ‘B’

Normal boiling point of the solution of any composition will always be less than that of ‘A’

On distillation of the solution at constant pressure of 1atm, the distillate will have pure liquid ‘B’ and the residual liquid will be pure liquid ‘A’.

If a small amount liquid ‘B’ is added in the liquid solution, the normal boiling point of solution will decrease.
