Q: What is the correct answer for this exam Chemistry Q61?

The correct answer is D. Sol. A. $[NiCl_4]^{2-}$: Ni is in +2 oxidation state ($3d^8$). $Cl^-$ is a weak field ligand. Hybridization $sp^3$, tetrahedral, paramagnetic (2 unpaired electrons). Correct.B. $[Ni(NH_3)_6]^{2+}$: Ni is in +2 oxidation state ($3d^8$). $NH_3$ is a strong field ligand, but for $Ni^{2+}$ it acts as a weak field ligand in octahedral complexes. Hybridization $sp^3d^2$, octahedral, paramagnetic (2 unpa

FirstInTest · Accepted Answer

Sol. A. $[NiCl_4]^{2-}$: Ni is in +2 oxidation state ($3d^8$). $Cl^-$ is a weak field ligand. Hybridization $sp^3$, tetrahedral, paramagnetic (2 unpaired electrons). Correct.B. $[Ni(NH_3)_6]^{2+}$: Ni is in +2 oxidation state ($3d^8$). $NH_3$ is a strong field ligand, but for $Ni^{2+}$ it acts as a weak field ligand in octahedral complexes. Hybridization $sp^3d^2$, octahedral, paramagnetic (2 unpaired electrons). Correct.C. $[Ni(CO)_4]$: Ni is in 0 oxidation state ($3d^{10}4s^0$). CO is a strong field ligand. Hybridization $sp^3$, tetrahedral, diamagnetic. Correct.D. $[Ni(CN)_4]^{2-}$: Ni is in +2 oxidation state ($3d^8$). $CN^-$ is a strong field ligand. Hybridization $dsp^2$, square planar, diamagnetic. Correct.All statements A, B, C, D are correct.
