$H_2S$

Vedclass · Answer

(B) The boiling point of hydrides of Group $16$ elements depends on the molecular mass and the presence of intermolecular hydrogen bonding. $H_2O$ has the highest boiling point due to extensive intermolecular hydrogen bonding. As we move down the group from $S$ to $Te$,the molecular mass increases,leading to stronger van der Waals forces,which increases the boiling point. Comparing the values: $H_2O$: $373 \ K$$H_2S$: $213 \ K$$H_2Se$: $232 \ K$$H_2Te$: $269 \ K$ Therefore,$H_2S$ has the lowest boiling point.
