Statements about heavy water are given below:
(A) Heavy water is used in exchange reactions for the study of reaction mechanisms.
(B) Heavy water is prepared by exhaustive electrolysis of water
(C) Heavy water has higher boiling point than ordinary water.
(D) Viscosity of \(\mathrm{H}_{2} \mathrm{O}\) is greater than \(\mathrm{D}_{2} \mathrm{O}\).
Choose the most appropriate answer from the options given below:
[JEE Main 2021, 26 Feb (Shift 1)]
(A), (B) and (C) only
(b) Heavy water \(\left(\mathrm{D}_{2} \mathrm{O}\right)\) is used in organic reaction to know about the kinetics of reaction.
Heavy water \(\mathrm{D}_{2} \mathrm{O}\) is obtained by carried out repeated electrolysis of \(\mathrm{H}_{2} \mathrm{O}\).
Heavy water has b.p \(101.4^{\circ} \mathrm{C}\) while ordinary water has b.p \(100^{\circ} \mathrm{C}\)
\(\mathrm{D}_{2} \mathrm{O}\) has more molecular mass as compared \(\mathrm{H}_{2} \mathrm{O}\), hence greater degree of association and as a result has greater b.p and viscosity.
