Melting point, enthalpy of vapourisation and viscosity data of H_(2)O and D_(2)O is given below:{:(,H_(2)O,D_(2)O),("Melting point/k",373.0,374.4),("Enthalpy of vapourisation at (373K)/KJ mol"^(-1),40.66,41.61),("Viscosity/centipoise",0.8903,1.107):} On the basis of this data explain in which of these liquids intermolecular forces are stronger?

Melting point, enthalpy of vapourisation and viscosity data of H_(2)O

1.	Melting point, enthalpy of vapourisation and viscosity data of H_(2)O and D_(2)O is given below:{:(,H_(2)O,D_(2)O),("Melting point/k",373.0,374.4),("Enthalpy of vapourisation at (373K)/KJ mol"^(-1),40.66,41.61),("Viscosity/centipoise",0.8903,1.107):} On the basis of this data explain in which of these liquids intermolecular forces are stronger?
Answer» Solution :The MELTING point, enthalpy of vaporization and viscosity values of all these items depend upon the intermolecular foreces of ATTRACTION . Since their values are highter for `D_(2)O` as compared to those of `H_(2)O`, THEREFORE, intermolecular forces of attraction are stronger in `D_(2)O` than in `H_(2)O`.
