Explain why H2O is in liquid state while H2S is in gaseous state at room temperature. |
|
Answer» H-O bond is more polar than H-S bond because of greater electronegativity difference in the bonding atoms. As a result, H2O molecules are involved in the intermolecular hydrogen bonding and get associated to be liquid at room temperature. Since intermoecular hydrogen bonding is negligible in the molecules of H2S, they do not get associated and remain in the gaseous state at room temperature. |
