Vedclass · Answer

(C) The molecular mass of $D_2O$ $(20 \ g/mol)$ is greater than $H_2O$ $(18 \ g/mol)$,so $H_2O Due to stronger hydrogen bonding in $D_2O$,its melting point $(3.82 \ ^\circ C)$ and boiling point $(101.4 \ ^\circ C)$ are higher than those of $H_2O$ ($0 \ ^\circ C$ and $100 \ ^\circ C$ respectively).Thus,the relation $B.P. = H_2O > D_2O$ is incorrect because $H_2O$ has a lower boiling point than $D_2O$.$D_2O$ has stronger chemical bonds (higher bond dissociation energy) than $H_2O$,making $H_2O$ more reactive than $D_2O$.
