The mixture that forms a maximum boiling azeotrope is

Components of a binary mixture of two liquids $A$ and $B$ were being separated by distillation. After some time,the separation of components stopped and the composition of the vapour phase became the same as that of the liquid phase. Both the components started coming in the distillate. Explain why this happened.

If two liquids $A$ and $B$ form a minimum boiling azeotrope at some specific composition,then which statement among the following is correct?

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?

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?

Rectified spirit is a mixture of
