Question:
Which of the following property is less for D₂O than H₂O?
Which of the following property is less for D₂O than H₂O?
Show Hint
The differences in physical properties between D₂O and H₂O are mostly due to the isotope effect, with D₂O being denser and having lower dielectric constant.

The Correct Option is A
Solution and Explanation
Deuterium oxide (D₂O) has a higher mass than H₂O due to the heavier deuterium isotope. As a result, its dielectric constant is lower than that of H₂O, while other properties like viscosity, density, and melting point are relatively similar.
