# Is it true that the stronger the intermolecular interactions the higher the vapor pressure?

Here we define boiling point as the temperature at which the vapour pressure of the liquid becomes equal to the ambient pressure, and bubbles of vapour form directly in the liquid. The normal boiling point is specified when the ambient pressure is $1$ $a t m$, and thus the vapour pressure of the liquid, at its normal boiling point, is $1 \cdot a t m$.
