Q. Consider the following statements about the solutions formed by mixing two liquids. A. An ideal solution thus formed obeys Raoult's law throughout the composition range. B. Mixture of chloroform and acetone shows negative deviation from Raoult's law. C. Mixture of aniline and phenol shows positive deviation from Raoult's law. Choose the correct statements from the options given below:
A) A and C only
B) A and B only
C) B and C only
D) A only
Explanation
[Solution from source] An ideal solution obeys Raoult's law at every composition. Chloroform and acetone form a C–H···O hydrogen bond (negative deviation). Aniline and phenol also hydrogen-bond with each other, showing negative deviation, so C is false. Answer (2).
