Statement A : Ethanol and acetone show positive deviation from Raoult’s law. Statement B : Pure ethanol molecule show hydrogen bond and on adding acetone hydrogen bond between ethanol molecules breaks.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
Ethanol molecules shows hydrogen bonding. On adding acetone, its molecules get in between the host molecule and break some of hydrogen bonds between them. Due to weakening of interaction the mixture of ethanol and acetone shows the positive deviation from Raoult’s law.

A solution of two miscible liquids showing negative deviation from Raoult's law will have :
1 Increased vapour pressure, increased boiling point
2 Increased vapour pressure, decreased boiling point
3 Decreased vapour pressure, increased boiling point
In the solutions which show deviation from Raoult's law, more attractions are there between particles. As a result vapour pressure decreases and boiling point increases. So, the correct option is (3).

Explanation:
When a solution is formed by adding carbon disulphide to acetone , the dipolar interactions among the solute - solute and solvent - solvent molecules are stronger than solute - solvent interactions. Hence, this solution shows positive deviation from Raoult's law. So, the correct option is (4).
