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 in $D_2O$,its melting point $(3.8 \ ^\circ C)$ and boiling point $(101.4 \ ^\circ C)$ are higher than those of $H_2O$ ($0 \ ^\circ C$ and $100 \ ^\circ C$ respectively).$H_2O$ is more reactive than $D_2O$ due to the stronger $O-D$ bond compared to the $O-H$ bond.Therefore,the statement $B.P. = H_2O > D_2O$ is incorrect.
