Question

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 ordinary water is greater than that of heavy water.

Choose the correct statements(s).

• A. A and B only
• B. A and D only
• C. A, B and C only
• D. A and C only

Answer 1

The correct option is C A, B and C only

Heavy water is prepared by exhaustive electrolysis of water. It is used in exchange reactions for study of reaction mechanisms.

$\text{B.P. of ordinary water}=373K$
$\text{B.P. of heavy water}=374.4K$

$\text{Viscosity of ordinary water}=0.89centipoise$
$\text{Viscosity of heavy water}=1.107centipoise$
