1. It is extensively used as a moderator in nuclear reactors
2. It cannot be used in exchange reaction to study reaction mechanism
3. Viscosity of heavy water is relatively smaller than that of ordinary water
4. The dielectric constant of heavy water is smaller than that of ordinary water
Select the correct answer using the code given below:

• A. 1 and 2
• B. 2 and 3
• C. 3 and 4
• D. 1 and 4

Answer 1

The correct option is D 1 and 4

Properties of heavy water are:
1. It is extensively used as a moderator in nuclear reactors.
2. It can be used in exchange reaction to study reaction mechanism.
3. Viscosity of heavy water is relatively larger than that of ordinary water.
4. The dielectric constant of heavy water is smaller than that of ordinary water.

So Option D is correct that is statement 1 and 4
