Based on the nature of their intermolecular forces, which of the following liquid mixtures will cons — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

Positive deviations occur when A-B forces are weaker than A-A/B-B forces. Adding non-polar cyclohexane to polar ethanol breaks ethanol's H-bonds. Adding non-polar $CS_2$ to polar acetone breaks dipole interactions. Adding $CCl_4$ to methanol breaks methanol's H-bonds. Benzene and toluene (C) form an ideal solution.
