Expert Answer:

Water has london forces and hydrogen bonding while hydrogen sifide has only london forces. Hydrogen forces occur when hydrogen is attached to highly electronegative taom such as oxygen. It forms slightly negative charge on oxygen and slightly positive charge on hydrogen. Hydrohgen of one molecule attracts oxygen of another molecule. It forms dipole. It requires more energy to break these bonds. Therefore water has more B.P. than H2S
