A graph of vapour pressure and temperature for three different liquids X, Y and Z is shown below:

The following inferences are made:
(A) X has higher intermolecular interactions compared to Y.
(B) X has lower intermolecular interactions compared to Y.
(C) Z has lower intermolecular interactions compared to Y.
The correct inference(s) is are :

Options

A. A and C
B. A
C. B
D. complex formation

Explanation

At a particular temperature as intermolecular forces of attraction increases, vapour pressure decrease.
So intermolecular forces of attraction of X < Y < Z.
