MCQ

Assertion : Transition metals show variable valency.

Reason : Transition metals have a large energy difference between the $ns^2$ and $(n -1)d$ electrons.

A
If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
B
If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
✓
If the Assertion is correct but Reason is incorrect.
D
If both the Assertion and Reason are incorrect.

✓

Answer

Correct option: C.

If the Assertion is correct but Reason is incorrect.

c
The assertion is correct but the reason is false. Actually transition metal show variable valency due to very small difference between the $ns^2$ and $(n -1)d$ electrons.
