JEE PYQ: States Of Matter Question 13
Question 13 - 2020 (08 Jan Shift 1)
A graph of vapour pressure and temperature for three different liquids $X$, $Y$, and $Z$ is shown. 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:
(1) (A) and (C) (2) (A) (3) (B) (4) (C)
Show Answer
Answer: (3) (B)
Solution
Higher vapour pressure at a given temperature means weaker intermolecular forces. X has the highest vapour pressure, so X has lower intermolecular interactions compared to Y.
