Question

The number of unpaired electrons in Mn+3 is​

Answer 1

Answer:

Explanation:

Mn has [Ar] 3d(5) 4s(2) configuration.

Mn+³ has 3d(4)

Now these four electrons can be arranged in following ways

t2g(3) eg(1) octahedral weak field. 4 u.p. electrons

t2g(4) eg(0) octahedral strong field. 2 u.p. electrons

eg(2) t2g(2) tetrahedral weak field. 4 u.p. electrons

eg(4) t2g(0) tetrahedral strong field. 0 u.p. electrons
