Hydrogen Bond Interactions are formed between Hydrogen atom attached to more electronegative atom (F, O or N) of one molecule and highly electronegative atom (F, O or N) of another molecule. In case of methanol, hydrogen is bonded directly to oxygen atom and gets partial positive charge, this hydrogen atom interacts with Oxygen (Highly electronegative) atom of second molecule. Hydrogen bonding are stronger due to which methanol has greater b.p (64.7 ⁰C) as compared to methane (-161.5 ⁰C).
