The colour and magnetic nature of mangante ion `(MnO_(4)^(2-))` is

A

green, paramagnetic

B

purple, diamagnetic

C

green, diamagnetic

D

pruple, paramagnetic

Text Solution

Verified by Experts

The correct Answer is:
A
Oxidation state of Mn in `MnO_(4)^(2-)` is +6.
`Mn (+6) 1s^(2) 2s^(2)2p^(6)3s^(2)3p^(6)4s^(1)`
Hence , manganate ion `(MnO_(4)^(2-))` is paramagnetic due to presence of unpaired electron. Also, `MnO_(4)^(2-)` is green in colour.

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.

Assertion: KMnO_(4) is purple in colour due to charge transfer . Reason :There is no electron present in d-orbitals of maganese in MnO_(4)^(-))
