Reason (R) : Dielectric constant of ordinary water is more than that of heavy water.
The correct answer is:
Both (A) and (R) are true and (R) is the correct explanation of (A)
Both (A) and (R) are true but (R) is not the correct explanation of (A)
(A) is true, but (R) is not true
(A) is not true, but (R) is true
Which one of the following reactions represents the oxidising property of H2O2?
