Arrange these compounds in order of increasing boiling point. Explain your reasoning.
a. CH4 b. CH3CH3 c. CH3CH2CL d. CH3CH2OH
a, b, c, d, Boiling point increases with increasing intermolecular forces. The molecules increase in their intermolecular forces as follows: a, dispersion forces; b, stronger dispersion forces (broader electron cloud); c, dispersion forces and dipole-dipole interaction; d, dispersion forces, dipole-dipole interactions, and hydrogen bonding.
