Question

The correct order of their paramagnetic moment (spin only) is `P:[FeF_(6)]^(3-),Q:[CoF_(6)]^(3-)`
`R:[V(H_(2)O)_(6)]^(3+),S:[Ti(H_(2)O)_(6)]^(3+)`
A. `P gt Q gt R gt S`
B. `P lt Q lt R lt S`
C. `P = Q = R = S`
D. `P gt R gt Q gt S`

Answer 1

`(A) , (P) to Fe^(+3), n=5,(Q) to Co^(3+),n= 4 `
( R) `to V^(3+), n=2, (S) to Ti^(3+),n=1`
no = no. of unpaired electrons
