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.(A) is correct: an ideal solution obeys Raoult's law over the entire composition range. (B) is correct: chloroform and acetone show negative deviation (H-bonding between them). (C) is incorrect: aniline and phenol also show negative deviation from Raoult's law.

For an ideal solution, the correct option is:For an ideal solution at constant T and P: $\Delta_{mix}H=0$, $\Delta_{mix}V=0$, $\Delta_{mix}S>0$, $\Delta_{mix}G<0$ So the correct option is $\Delta_{mix}H=0$.
