Given below are two statements:
Assertion (A): Two liquids nitric acid and water form a maximum boiling azeotrope when mixed in the ratio of \(68\%\) and \(32\%\)respectively.
Reason (R): The interaction between nitric acid and water is stronger than nitric acid-nitric acid interactions and water-water interactions.
 
1. Both (A) and (R) are True and (R) is the correct explanation of (A).
2. Both (A) and (R) are True but (R) is not the correct explanation of (A).
3. (A) is True but (R) is False.
4. Both (A) and (R) are False.

On the basis of the information given below, mark the correct option.

i. In a bromoethane and chloroethane mixture, intermolecular interactions of A—A and B—B type are nearly the same as A—B type interactions.
ii. In an ethanol and acetone mixture, A—A or B—B type intermolecular interactions are stronger than A—B type interactions.
iii. In a chloroform and acetone mixture, A—A or B—B type intermolecular interactions are weaker than A—B type interactions.

1.  Solutions (ii) and (iii) will follow Raoult’s law

2.  Solution (i) will follow Raoult’s law

3.  Solution (ii) will show negative deviation from Raoult’s law

4.  Solution (iii) will show positive deviation from Raoult’s law

Components of a binary mixture of two liquids A and B were being separated by distillation. After some time, separation of components stopped and the composition of the vapor phase became the same as that of the liquid phase. Both the components started coming in the distillate. This happened due to:

1. Azeotropic mixture 2. Raoult's law
3. Ostwald dilution law 4. Colligative property
