Question

why water is liquid but H2S is gas​

Answer 1

In h2o there is hydrogen bonding because oxygen has a high electronegativity(only second to flourine). so, the hydrogen atoms from other molecules of water forms a hydrogen bonds with oxygen resulting in intermolecular hydrogen bonding. ... therefore at room temperature h2o is a liquid and h2s is a gas.

Answer 2

H2s is gas at room temperature not solid as it's boiling point is -60′c…. In water hydrogen bonding is responsible for the association of molecules, in turn to abnormally high boiling point. Hence H20 is liquid. Electronegativity of sulfur being less than that of oxygen, hydrogen bonding won't be observed.
