Question

Number of incorrect statements are-
(A) The $\pi$ bond between metal and carbonyl carbon reduces the boond order of $C-O$ in carbon monoxide
(B) $d{z}^2$ orbital. of central metal atom/ion is used in $ds{p}^2$ hybridisation.
(C) $C{N}^{-}$is a $\pi$ - acid Ligand.
(D) All negative ligands are stronger than neutral ligands.

Answer 1

Answer: 2

$(A)$ The $\pi$ bond between metal and carbonyl carbon reduces the bond order of $C-O$ in carbon monoxide $(C)$ $C{N}^{-}$is a $\pi$ - acid Ligand.
The above statements are correct.
$d_{x^2-y^2}$ orbital of central metal atom/ ion is used in $ds{p}^2$ hybridisation.
