4.
Explain why ethers generally have lower melting and boiling points than corresponding
alcohols with the same molar masses.
While ethers contain an oxygen, they do not have hydrogens attached to an oxygen. As a
result, they are not able to hydrogen bond with other ether molecules. Since the forces
between the ether molecules are weak dispersion forces, it does not take much energy to
separate them from each other and convert from solid to liquid or liquid to gas. Alcohols
can hydrogen bond and so more energy is required to separate molecules and the boiling
point or melting point goes up.
