$H_2O$

Vedclass · Answer

(A) The boiling point of hydrides of group $16$ elements generally increases down the group due to an increase in molecular mass and the resulting increase in van der Waals forces of attraction. However,$H_2O$ exhibits an anomalously high boiling point compared to other hydrides $(H_2S, H_2Se, H_2Te)$ because of the presence of strong intermolecular hydrogen bonding. Among the remaining hydrides,the boiling point follows the order: $H_2S Comparing $H_2O$ with $H_2Te$,the hydrogen bonding in $H_2O$ is significantly stronger,making its boiling point $(373 \ K)$ higher than that of $H_2Te$ $(269 \ K)$.
