Explanation:
In methane the intermolecular forces are the weak London dispersion forces. Water molecules are held together by hydrogen bonding.
- London dispersion forces are weak forces of attraction between molecules. It is a predominant in compounds that have very weak polarity.
- Hydrogen bonding is the electrostatic attraction between the hydrogen of one molecule and the electronegative atom(O or N or F) of a neighboring molecule.
Hydrogen bonds holds water molecules together. Since it is a stronger bond, it confers a higher boiling point
