The ratio of magnetic moment (spin only value) between `[FeF_(6)]^(3-)` and `[Fe(CN)_(6)]^(3-)` is approximatelyA. 4B. 2C. 5D. 3

Answer» Correct Answer - D
`mu` = `sqrt n(n+2)` B.M
For `[Fe(CN)_6]^(3-)` , n = 1 , `mu` `sqrt 1(1+2)` = 173 B.M
For `[FeF_6]^(3-)` , n = 5
`mu` = `sqrt 5(5 + 2)` = 5.92 B.M
Ratio = `5.92 / 1.73 = 3.`
