Question

The type of magnetism exhibited by ${\left[Mn{\left(H_{2}O\right)}_6\right]}^{2+}$ ion is paramagnetic.

• A. True
• B. False

Answer 1

The correct option is A True

${\left[Mn{\left(H_{2}O\right)}_6\right]}^{2+}$ is paramagnetic.

Electronic configruation of $M{n}^{+2}$ is $\left[Ar\right]3d^5$

$H_{2}O$ is intermediate ligand and in both the cases:

Pairing of electrons leaves $M{n}^{+2}$ configuration with 1 unpaired

Non pairing of electrons makes $M{n}^{+2}$ configuration with 5 unpaired electrons.

So in either cases the given complex is paramagentic.

So given statement is True.
