Methane is a completely symmetrical nonpolar molecule. Methanol has an -OH group attached to the CH3. The slightly positive H's attached to OH are attracted to the slightly negative O's. This leads to the attraction of methanol molecules for one another and to the higher boiling point of methanol.

Because of the O-H bond in methanol, the attraction between CHO3H are hydrogen bonds. the hydrogen atoms in methane, CH3 are bounded to carbon not oxygen, so there is no hydrogen bond for methane.
The strong hydrogen bonds of methanol require more heat energy to overcome the bonds during boiling.
