At ordinary temperature H\(_2\)O is a liquid while H\(_2\)S is a gas. This is because H\(_2\)O has
weak intermolecular forces holding its molecules together
strong hydrogen bonds holding its molecules together
induced dipole-induced dipole forces between its molecules
ionic force between its molecules

H\(_2\)O has stronger intermolecular dipole--dipole interaction because of the greater polarity (or a hydrogen bond). Because of the stronger intermolecular interaction H\(_2\)O is more stable and exists as a liquid.
