B. Liquid B is polar and liquid A in nonpolar, and the stronger intermolecular forces in liquid B
give the liquid a lower vapor pressure.
What effect does polarity have on boiling and melting points of compounds?
The polarity of molecules brings them closer to each other due to attractions between opposite
poles . So high amount of energy is required to covert the liquid into vapours, so such liquids
have high boiling point. A more polar molecule will have a higher melting point. A polar
molecule will have a strong dipole-dipole bond and will require more energy to break that bond.
