Question

Which of the following property indicates weak intermolecular forces of attraction in liquid?

• A. High heat of vaporization
• B. High vapour pressure
• C. High critical temperature
• D. High boiling point

Answer 1

Answer: (B)

High vapour pressure

The molecules that are having weak intermolecular forces of attraction, they can easily dissociate and convert into vapour state,

so, molecules with weak intractions have high vapour pressure.

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