QJEEM22Ch2cc0: JEE Main 2022 Chemistry - Class 12 JEEM22Ch2cc0 Solution: The spin-only magnetic moment value of the compound with…

The spin-only magnetic moment value of the compound with strongest oxidizing ability among MnF4,MnF3\mathrm{MnF}_{4}, \mathrm{MnF}_{3} and MnF2\mathrm{MnF}_{2} is ____________ B.M. [nearest integer]

Step-by-Step Verified Solution

MnF3\mathrm{MnF}_{3} has the strongest oxidizing ability

[EMn+3/Mn+2∘≃1.57 V&  EMn+4/Mn+2∘≃1.2 V]\left[\begin{array}{l}\mathrm{E}_{\mathrm{Mn}^{+3} / \mathrm{Mn}^{+2}}^{\circ} \simeq 1.57 \mathrm{~V} \\\& \,\,\mathrm{E}_{\mathrm{Mn}^{+4} / \mathrm{Mn}^{+2}}^{\circ} \simeq 1.2 \mathrm{~V}\end{array}\right]

So, spin only magnetic moment

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

≃5\simeq 5
