Solution

The correct options are
A May show positive or negative deviation from Raoult's law
D Behave like single pure component and boil at a fixed temperature
Azeotropes are a mixture of at least two different liquids. Their mixture can either have a higher boiling point than either of the components or they can have a lower boiling point. Azeotropes occur when the fraction of the liquids cannot be altered by distillation.

They have a constant boiling point like pure compound because the vapour has the same composition as the liquid mixture. The boiling point of an azeotropic mixture may be higher or lower than that of any of its components.

Hence, options B and D are correct.

Q. A solution made up of mixing two liquids A and B forms an azeotropic mixture at a given composition. Given that pure liquid A boils at lower temperature than pure liquid B, then on fractional distillation of the azeotropic mixture:

Q. CASE1: Read the passage given below and answer the following question.

The solution which obeys Raoult’s law over the entire range of concentration are known as ideal solutions. The solution which does not obey Raoults law over the entire range of concentration, then it is called non-ideal solution. The vapour pressure of such as a solution is either higher or lower than that predicted by Raoult’s law. If it is higher, the solution exhibits positive deviation and if it is lower, it exhibits negative deviation from Raoult’s law.
Some liquids on mixing, form azeotropes which are binary mixture having the same composition in liquid and vapour phase. There are two types of azeotropes. Minimum boiling azeotropes and maximum boiling azeotropes.
