Question

How many unpaired electron (s) is/are present in $t_{2}g$ orbitals of ${\left[Mn{\left(N{H}_3\right)}_6\right]}^{2+}$.

Answer 1

Answer: 3

${\left[Mn{\left(N{H}_3\right)}_6\right]}^{2+}⟶$ Exception case $⟶$ Even through $N{H}_3$ is a $S.F.L$ but experimentally pairing of electron is not observed.
