Because methane molecules are nonpolar and do not form
hydrogen bonds with each other, whereas water molecules
are polar and freely form hydrogen bonds

Because methane molecules are polar and form hydrogen
bonds with each other, whereas water molecules are
nonpolar and do not form hydrogen bonds

Because C-H bonds in methane molecule have a very large
electronegativity difference, whereas O-H bonds
in water molecules have a very small electronegativity difference

Because methane molecule has a bent geometry.
whereas water molecule has a regular geometry
