Question

Number of incorrect statements are‐

$\left(A\right)$ The $\pi$ bond between metal and carbonyl carbon reduces the bond order of $C-O$ in carbon monoxide

$(B)d{z}^2$ orbital of central metal atom/ ion is used in $ds{p}^2$ hybridisation.

$\left(C\right)C{N}^{-}$ is a $\pi ‐$ acid Ligand.

$\left(D\right)$ All negative ligands are stronger than neutral ligands.

Answer 1

Answer: 2

$\left(A\right)$ The $\pi$ bond between metal and carbonyl carbon reduces the bond order of $C-O$ in carbon monoxide

$\left(C\right)C{N}^{-}$ is a $\pi ‐$ acid Ligand.

The above statements are correct.

${\text{d}}_{{\text{x}}^{\text{2}}-{\text{y}}^{\text{2}}}$ orbital of central metal atom/ ion is used in $ds{p}^2$ hybridisation.
