Answer:
Correct Answer: 15.(b)
Solution:
- (b) Heavy water is used for slowing down the speed of neutrons and used as moderators. Boiling point of heavy water is more than that of ordinary water, so it is more associated. The dielectric constant of heavy water is slightly les than that of ordinary water. Hence, ordinary water is more effective solvent than heavy water.
