Question

A graph of vapour pressure and temperature for the three different liquids $X,Y$ and $Z$ is shown:
The following interference are made:
$\left(A\right)X$ has higher intermolecular interaction compared to $Y$.
$\left(B\right)X$ has lower intermolecular interaction compared to $Y$.
$\left(C\right)Z$ has lower intermolecular interaction compared to $Y$.
The correct interfernce(s) is/are:

• A. $\text{(A) and (C)}$
• B. $\text{(A)}$
• C. $\text{(C)}$
• D. $\text{(B)}$

Answer 1

The correct option is D $\text{(B)}$

Only statement $\left(B\right)$ i.e. $\left(X\right)$ has lower intermolecular interactions as compared to $\left(Y\right)$ is correct beacuse at a particular temperature the vapour pressure decreases intermolecular interaction increases.


Hence, the correct option is $\left(d\right)$.
