Expert Answer:

Hydrogen sulfide has a structure similar to that of water. H2O has 104.50 and H2S has 92.10This is where the similarity ends, however.  Sulfur is not nearly as electronegative as oxygen so that hydrogen sulfide is not nearly as polar as water.  Because of this, comparatively weak intermolecular forces exist for H2S and the melting and boiling points are much lower than they are in water.  Hydrogen sulfide and water boil at -60.7 oC and +100.0 oC , respectively.
