Heavy water (D2O) is used in organic reaction to know the kinetics of reaction
Heavy water D2O is obtained by repeated electrolysis of H2O.
Heavy water has b.pt 101.4°C and ordinary water has b.pt 100°C
(b.pt of D2O > b.pt of H2O)
D2O has more molecular mass than H2O, so greater degree of association and hence greater b.pt and viscosity.
