Question

Explain why h2o is liquid while h2s is gas gaussian

Answer 1

h2ois liquid because of Strong H-bonding found between oxygen and hydrogen while there is no such case in h2s

Answer 2

The reason is that molecules of water form hydrogen bonds between them. ... Each H2O molecule has 4 H-bonds with other H2O molecules. H2S doesn't have H-bond. Hence, H2O has more intermolecular attractions compared to H2S and hence, H2O is a liquid while H2S is a gas at room temperature
