Explain why H2O is liquid while H2S is a gas.

Asked by Topperlearning User | 9th Oct, 2014, 08:36: AM

Expert Answer:

The water molecules are associated with one another by strong intermolecular hydrogen bonds, whereas the intermolecular forces in liquid H2S are weak dipole-dipole forces.

As a result, the boiling point of H2S is much lower than that of H2O.

So at ordinary temperature H2O is liquid whereas H2S is gas.
