Chemistry Question on Organic Chemistry- Some Basic Principles and Techniques

The spin-only magnetic moment value of the compound with strongest oxidizing ability among MnF4, MnF3 and MnF2 is____ B.M. [nearest integer]

Answer

MnF3 has the strongest oxidising ability

[EºMn3+/Mn2+∘≃1.57V &EºMn4+/Mn2+∘≃1.2V]\begin{bmatrix} EºMn3+/Mn2+∘≃1.57 V& \\\ \& EºMn4+/Mn2+∘≃1.2 V & \end{bmatrix}

So, spin only magnetic moment

=4(4+2)=24=\sqrt{4(4+2)}=\sqrt24 B.M.
