Answer
If a compound contains an alcohol (-OH) group, it would contain hydrogen bonds, because the hydrogen would be attracted to the unshared pair on the oxygen. Therefore, its boiling point would be higher - more energy would be required to break them apart. Dimethyl ether cannot contain hydrogen bonds.
