Question

(ii) H2O occurs in a liquid state while H2S is a gas at room temperature and pressure.

Answer 1

Answer:

H2O is liquid because of its ability to form hydrogen bonds which is possible only in case of F , O and N because of their high electronegativity. While in case of H2S there is no hydrogen bond formation . Hence H20 is liquid while H2S is gas .
