Which of the following does not show positive deviation from Raoult's law?

If liquids $A$ and $B$ form an ideal solution,then:

Two statements are given below:
Statement-$I$: Liquids $A$ and $B$ form a non-ideal solution with positive deviation. The interactions between $A$ and $B$ are weaker than $A-A$ and $B-B$ interactions.
Statement-$II$: For an ideal solution,$\Delta_{mix} H = 0$ and $\Delta_{mix} V = 0$.
The correct answer is:

Which of the following statements about the composition of the vapour over an ideal $1:1$ molar mixture of benzene and toluene is correct? Assume that the temperature is constant at $25\ ^oC$. (Given,vapour pressure data at $25\ ^oC$,benzene $= 12.8\ kPa,$ toluene $= 3.85\ kPa$)

What role does the molecular interaction play in a solution of alcohol and water?

Liquids $A$ and $B$ form an ideal solution. Which of the following statements is true?
