Assertion `(A) :` In radioactive disintegrations, `._(2)H^(4)` nuclei can come out of the nucleus but lighter `._(2)H^(3)` cannot.
Reason `(R) :` The binding energy of `._(2)H^(3)` is more than that of `._(2)H^(4)`.

A

If both `(A)` and `(R)` are correct , and `(R)` is the correct explanation of `(A)`

B

If both `(A)` and `(R)` are correct, but (R) is not the correct explanation of `(A)`

C

If `(A)` is correct, but `(R)` is incorrect.

D

If `(A)` is incorrect, but `(R)` is correct.

Text Solution

Verified by Experts

The correct Answer is:
C
Radioactive disintegration reaction produces stable nuclei, till that the nuclei undergo the process. The `._(2)He^(4)` nuclei is more stable than `._(2)He^(3)` nuclei. Hence, it is proceed in radioactive reaction.
