Which of the following azeotropic solutions has the boiling point less than boiling point of the constituents A and B?
1 \(\mathrm{CHCl}_{3}\) and \(\mathrm{CH}_{3} \mathrm{COCH}_{3}\)
2 \(\mathrm{CS}_{2}\) and \(\mathrm{CH}_{3} \mathrm{COCH}_{3}\)
3 \(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH}\) and \(\mathrm{CH}_{3} \mathrm{COCH}_{3}\)
4 \(\mathrm{CH}_{3} \mathrm{CHO}\) and \(\mathrm{CS}_{2}\)
Explanation:
When the intermolecular interactions are weaker than those of the pure constituents, the boiling point of the resultant solution is less than that of the constituents. Such condition is found in case of non - ideal solution showing positive deviation from Raoult's law. Among the given, solution of \(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH}\) and \(\mathrm{CH}_{3} \mathrm{COCH}_{3}\) and solution of \(\mathrm{CS}_{2}\) and \(\mathrm{CH}_{3} \mathrm{COCH}_{3}\) are non - ideal and show positive deviations. Hence, they have lesser boiling points or higher vapour pressures.

Components of a binary mixture of two liquids A and B were being separated by distillation. After some time separation of components stopped and composition of vapour phase became same as that of liquid phase. The binary mixture is
1 An ideal solution
2 An azeotrope
3 Isotonic
4 Hypertonic
Explanation:
Since both the components are appearing in the distillate and composition of liquid and vapour is same, this shows that liquids have formed azeotropic mixture and hence cannot be separated at this stage by distillation.
