The boiling point of water is higher than the boiling point of ethanol because
the bonding in water is electrovalent (ionic) whereas the bonding in ethanol is convalent
the hydrogen bonding between water molecules is stronger than the hydrogen bonding between ethanol molecules
water has a higher lattice energy than ethanol.
water has hydrogen bonding between its molecules but ethanol has no hydrogen bonging between its molecules;
water is a better solvent than ethanol.
