Question

The d-electron configuration of [Ru(en)3]Cl2 and [ Fe ( H 2 O )6] Cl 2, respectively are: (A) t 2 g 4 e g 2 and t 2 g 6 e g 0 (B) t 2 g 6 e g 0 and t 2 g 6 e g 0 (C) t 2 g 6 e g 0 and t 2 g 4 e g 2 (D) t 2 g 4 e g 2 and t 2 g 4 e g 2

[Ru(en)3]Cl2 Ru ⇒ 4d series en ⇒ chelating ligand CN =6, octahedral splitting hence large splitting of d-subshell

[ Fe ( H 2 O )6] Cl 2 ⇒ H 2 O ⇒ Weak filled ligand Fe +2 ⇒ [ Ar ] 3d 6 4s 0 less splitting CN =6 octahedral splitting

Q. The d-electron configuration of $[R u (e n)_{3}] C l_{2}$ and $[F e (H_{2} O)_{6}] C l_{2}$ , respectively are:

$t_{2 g}^{4} e_{g}^{2}$ and $t_{2 g}^{6} e_{g}^{0}$

$t_{2 g}^{6} e_{g}^{0}$ and $t_{2 g}^{6} e_{g}^{0}$

$t_{2 g}^{6} e_{g}^{0}$ and $t_{2 g}^{4} e_{g}^{2}$

$t_{2 g}^{4} e_{g}^{2}$ and $t_{2 g}^{4} e_{g}^{2}$

Q. The d-electron configuration of [Ru(en)3​]Cl2​ and [Fe(H2​O)6​]Cl2​, respectively are:

t2g4​eg2​ and t2g6​eg0​

t2g6​eg0​ and t2g6​eg0​

t2g6​eg0​ and t2g4​eg2​

t2g4​eg2​ and t2g4​eg2​

[Ru(en)3​]Cl2​ Ru⇒4d series en ⇒ chelating ligand CN=6, octahedral splitting hence large splitting of d-subshell [Fe(H2​O)6​]Cl2​⇒H2​O⇒ Weak filled ligand Fe+2⇒[Ar]3d64s0 less splitting CN=6 octahedral splitting
