Vedclass · Answer

(C) The molecular mass of $D_2O$ $(20 \ g/mol)$ is greater than $H_2O$ $(18 \ g/mol)$.Due to stronger hydrogen bonding and higher molecular mass,$D_2O$ has a higher melting point and boiling point than $H_2O$.Therefore,the boiling point $(B.P.)$ relation $H_2O > D_2O$ is incorrect; the correct relation is $H_2O $H_2O$ is more reactive than $D_2O$ due to the stronger $O-D$ bond compared to the $O-H$ bond.
