H2S is a gas while H2O is  a liquid .Why?
Asked by Ibrahim Mohammed | 05 Feb, 2015, 04:33: AM
answered-by-expert Expert Answer
H2O has intermolecular hydrogen bond between it's molecule (H-O-H------H-O-H) while H2S has weak van der Waals forces between it's molecule. Hence the molecules of H2O are strongly packed than H2S, thus water is at liquid state at room temperature.
