Q. Assertion : Azeotropic mixtures are formed only by non - ideal solutions and they may have boiling points either greater than both the components or less than both the components.
Reason : The composition of the vapour phase is same as that of the liquid phase of an azeotropic mixture.

Q. Assertion :For an azeotropic solution, the composition of vapour at its boiling point is same as that of liquid solution. Reason: A mixture of benzene and

Q. CASE 1: 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.
