हिन्दीConsider 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 option:
Correct answer · Option 1
A and B only
Explanation
An ideal solution obeys Raoult's law across all concentrations (Statement A is correct). Chloroform and acetone form strong hydrogen bonds, showing negative deviation (Statement B is correct). Aniline and phenol show negative deviation due to intermolecular H-bonding between aniline \( -NH_2 \) and phenol \( -OH \), not positive deviation (Statement C is incorrect).
