Question

Match the electronic configurations in List-I with appropriate metal complex ions in List-II and choose the correct option.
[Atomic Number: Fe = 26, Mn = 25, Co = 27]
| List-I| | List-II
---|---|---|---
(P)| $t^6_{2g} e^0_g$| (1)| $[Fe(H_2O)_6]^{2+}$
(Q)| $t^3_{2g} e^2_g$| (2)| $[Mn(H_2O)_6]^{2+}$
(R)| $e^2t^3_{2}$| (3)| $[Co(NH_3)_6]^{3+}$
(S)| $t^4_{2g} e^2_g$| (4)| $[FeCl_4]^-$
| | (5)| $[CoCl_4]^{2-}$
