The number of unpaired electrons in gaseous species of `Mn^(3+), Cr^(3+)` and `V^(3+)` respectively are………….and most stable species is…………..

A

4, 3 and 2 `V^(3+)` is most stable

B

3, 3 and 2 and `Cr^(3+)` is most stable

C

4, 3 and 2 `Cr^(3+)` is most stable

D

3, 3 and 3 and `Mn^(3+)` is most stable

Text Solution

Verified by Experts

The correct Answer is:
C
Fully filled or half-filled structure favours stability.

No. of unpaired electrons = 2
`Cr^(3+)` is most stable species.
