Question

Which hydride is not found in liquid state?

Answer 1

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.

hope it helps

Answer 2

because of hydrogen bond..
