Q. How many unpaired electron (s) is/are present in $t_{2} g$ orbitals of $\left[ Mn \left( NH _{3}\right)_{6}\right]^{2+}$.
Coordination Compounds
Solution:
$\left[ Mn \left( NH _{3}\right)_{6}\right]^{2+} \longrightarrow$ Exception case $\longrightarrow$ Even through $NH _{3}$ is a $S.F.L$ but experimentally pairing of electron is not observed.
