The spin-only magnetic moment value of the compound with strongest oxidizing ability among MnF 4 , MnF 3 and MnF 2 is_____ B . M (nearest integer)

Step-by-step solution

The change from Mn 3 + to Mn 2 + results in the half-filled (d 5 ) configuration which has extra stability.So, MnF 3 has most oxidising tendency. Hence, MnF 3 has the strongest oxidizing ability as it undergoes reduction readily. Spin only magnetic moment is calculated using the following formula μ = n n + 2 B . M μ = 4 4 + 2 = 24 = 4 . 89 = 5   B . M
