Question

A graph of vap our 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 :

• A. (C)
• B. (A)
• C. (B)
• D. (A) and (C)

Answer 1

Answer: (C)

(B)

Answer 2

Order of $B.P.$ is :$Z > Y > X$
Order of vapour pressure : $Z < Y < X$
order of intermolecular interaction : $Z > Y > X.$
