Assetion : The green manganate is paramagnetic but the pruple permanganate is diamagnetic in nature.
Reason : `MnO_(4)^(2-)` contains on upaired electron while in `MnO_(4)^(-)` all electrons are paried.

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:
A
Assertion: Correct statement and reason is correct explanation of assertion.
Green `rarr MnO_(4)^(-) - [Ar]^(18) 3 d^(1) 4 s^(0)`, there is one upaired electron, so paramagnetic.
Purple `rarr MnO_(4)^(2-) - [Ar]^(18) 3 d^(0) 4s^(0)`, here all electrons are paried, so diamagnetic.
