Vedclass · Answer

(D) $1$. $[Ni(CO)_4]$: $Ni$ is in $0$ oxidation state $(3d^8 4s^2)$. $CO$ is a strong field ligand,causing pairing. Hybridisation is $sp^3$ $(I)$.$2$. $[Cu(NH_3)_4]^{2+}$: $Cu^{2+}$ is $3d^9$. The unpaired electron is in $4p_z$,and the hybridisation is $dsp^2$ $(II)$.$3$. $[Fe(NH_3)_6]^{2+}$: $Fe^{2+}$ is $3d^6$. $NH_3$ is a strong field ligand,causing pairing. Hybridisation is $d^2sp^3$ $(IV)$.$4$. $[Fe(H_2O)_6]^{2+}$: $Fe^{2+}$ is $3d^6$. $H_2O$ is a weak field ligand,no pairing. Hybridisation is $sp^3d^2$ $(III)$.Thus,the correct match is $A-I, B-II, C-IV, D-III$.
