$H_2O$ because of hydrogen bonding

Vedclass · Answer

(A) The boiling points of hydrides of group $16$ elements depend on both molecular mass and intermolecular forces. As we move down the group from $O$ to $Te$,the molecular mass increases,which leads to an increase in van der Waals forces,generally increasing the boiling point. However,$H_2O$ molecules are held together by strong intermolecular hydrogen bonding,which is absent in the other hydrides ($H_2S$,$H_2Se$,$H_2Te$). Due to this strong hydrogen bonding,$H_2O$ has an anomalously high boiling point compared to the other hydrides in the series.
