Question

The colour and magnetic nature of manganate ion (MnO2-4) is (A) green, paramagnetic (B) purple, diamagnetic (C) green, diamagnetic (D) purple, paramagnetic

Tardigrade Admin · Accepted Answer

In MnO4-2 oxidation state of Mn is +6 Its electronic configuration is 1 s2 2 s2 2p6 3 s2 3 p6 3 d1, 4 s0 Due to presence of unpaired electron it is coloured and paramagnetic. And it's colour is purple.

Q. The colour and magnetic nature of manganate ion $(M n O_{4}^{2 -})$ is

green, paramagnetic

purple, diamagnetic

green, diamagnetic

purple, paramagnetic

In $M n O_{4}^{- 2}$ oxidation state of $M n$ is $+ 6$
Its electronic configuration is $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{1}, 4 s^{0}$
Due to presence of unpaired electron it is coloured and paramagnetic. And it's colour is purple.
