CBSE Class 12-science Answered

why water is a liquid and H2S is gas at room temperature?
Asked by Yatin gupta | 31 Dec, 2012, 12:59: AM
Expert Answer
This is because, H20 has intermolecular hydrogen bond between it's molecule (H-O-H------H-O-H) while H2S has weak Van Der Wals forces between it's molecule.Hence the molecules of H2O are strongly packed than H2S,thus water is at liquid state at room temperature,
