Q. Which of the following pair is not correctly matched?
A) Absorption peak for $\left\lbrack Cr^{III}\left( NH_{3} \right)_{6} \right\rbrack^{3 +} = 21680$ $cm^{- 1}$
B) Effective atomic no. of Pt in $\left\lbrack PtCl_{6} \right\rbrack^{2 -} = 84$
C) Crystal field stabilization energy of $d^{2}$ in weak ligand field $= ( - )0.8{\ \mathrm{\Delta}}_{0}$
