If more of a liquid evaporates, does that mean it has stronger intermolecular forces

No

Explanation:

The stronger the intermolecular forces the molecules tend to stay in the liquid phase. Compounds with weak intermolecular forces are more volatile and more molecules overcome those forces to pass to the gas phase.
