Question
Identify the CORRECT set of details from the following :
A. $\left\lbrack Co\left( {NH}_{3} \right)_{6} \right)^{3 +}$ : Inner orbital complex ; $d^{2}$ sp $\ ^{3}$ hybridized
B. $\left\lbrack {MnCl}_{6} \right\rbrack^{3 -}$ Outer orbital complex; sp $\ ^{3}$ hybridized
C. $\left\lbrack {CoF}_{6} \right\rbrack^{3}$ : Outer orbital complex ; $d^{2}{sp}^{3}$ hybridized
D. $\left\lbrack {FeF}_{6} \right\rbrack^{3}$ : Outer orbital complex: ${sp}^{3}{\text{ }d}^{2}$ hybridized
E. $\left\lbrack Ni(CN)_{4} \right\rbrack^{2 -}$ : Inner orbital complex ; sp $\ ^{3}$ hybridized
Choose the correct answer from the options given below:
Options
Solution
A) ${Co}^{3 +}: - 3{\text{ }d}^{6}$
${NH}_{3} \Rightarrow$ S.F.L
Hybridisation $\Rightarrow d^{2}{sp}^{3}$, Inner orbital complex
B) ${Mn}^{3 +}: - 3{\text{ }d}^{4}$
${Cl}^{-} \Rightarrow$ W.F.L
Hybridisation $\Rightarrow {sp}^{3}{\text{ }d}^{2}$, Outer orbital complex
C) ${Co}^{3 +}: - 3{\text{ }d}^{6}$
$F^{-} \Rightarrow$ W.F.L
Hybridisation $\Rightarrow {sp}^{3}{\text{ }d}^{2}$, Outer orbital complex
D) ${Fe}^{3 +}: - 3{\text{ }d}^{5}$
$F^{-} \Rightarrow$ W.F.L
Hybridisation $\Rightarrow {sp}^{3}{\text{ }d}^{2}$, Outer orbital complex
E) ${Ni}^{2 +}: - 3{\text{ }d}^{8}$
${CN}^{-} \Rightarrow$ S.F.L
Hybridisation ⇒ dsp $\ ^{2}$, Inner orbital complex
