Two liquids A and B form type II non-ideal solution which shows a minimum in its temperature-molefraction plot (T-X diagram). Can the two liquids be completely separated by fractional distillation?

Explanation

Two liquids A and B form type II non-ideal solution which shows a minimum in its temperature-mole fraction plot can not be completely separated by fractional distillation because they form a constant boiling azeotropic mixture thus, upon fractional distillation either A or B is obtained pure along with composite composition.
