t_{2g}^3 e_g^2

Solution:

[\mathrm{Mn}(\mathrm{H}_2\mathrm{O})_6]^{2+}

has

t_{2g}^3 e_9^2

configuration

\mathrm{H}_2\mathrm{O}

is a weak field ligand, means it does not cause pairing of

\mathrm{e}^{-}

The

3d

electron will occupy the

d

-orbital with 5 -single electrons is each orbital.

d

splits into

t_{2g}

has 3 electrons and

e_g

has 2 electrons.
