The boiling point of an azeotropic mixture of water and ethanol is less than that of both pure water and pure ethanol. The mixture shows:

The boiling point of an azeotropic mixture of water-ethanol is less than that of both water and ethanol. Then

Why is it not possible to obtain pure ethanol by fractional distillation? What general name is given to binary mixtures which show deviation from Raoult’s law and whose components cannot be separated by fractional distillation? How many types of such mixtures are there?

Which of the following binary mixtures does not show the behavior of minimum boiling azeotropes?

Which of the following mixtures is known as rectified spirit?

Water (boiling point $100^\circ C$) and $HCl$ (boiling point $85^\circ C$) form an azeotropic mixture at $108.5^\circ C$. What is obtained when this mixture is distilled?
