Assertion : Manganese show a maximum oxidation state of `+ 5`.
Reason : Manganese has 5 electrons in the `3d` subshell.

A

If both assetion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are ture but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
Correct Assertion : Manganese show a maximum oxidation state of `+ 7` (as it has `3 d^(5) 4 s^(2)` configuration and the energy difference between `3d` and `4s` subshell is small).
