Question

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 inferences is/are

Select the correct option:

(B)

(C)

(A) and (C)

(A)

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

Vapour pressure of a liquid at a given temperature is inversely proportional to intermolecular force of attraction. At the same temperature, vapour pressure of X is higher than that of Y.
Therefore (X) has lower intermolecular interactions compared to Y. Statement (B) is correct.
