Question

Which of the following pairs is not correctly matched.

• A. Effective atomic number of $Pt$ in $\left\lbrack PtCl_{6} \right\rbrack^{2 -} = 84$
• B. Absorption peak for $\left\lbrack Cr^{III}(NH_{3})_{6} \right\rbrack^{+ 3} = 21680cm^{- 1}$
• C. Crystal field stabilization energy of $d^{2}$ in weak ligand field $= ( - )0.8\Delta_{0}$
• D. Example of weak ligand field for $d^{5}$ configuration $= \left\lbrack Mn^{II}F_{6} \right\rbrack^{- 4}$

Answer 1

Answer: (A)

Effective atomic number of $Pt$ in $\left\lbrack PtCl_{6} \right\rbrack^{2 -} = 84$

Answer 2
