Which are π-bonded organometallic compounds?a)[Cr(η6 —...

Explanation:

Bonded organometallic compounds:

- [Cr(6 (C6H6)]: This compound contains a benzene ligand bonded to a chromium atom. The bond between the benzene ligand and the chromium atom is a π-bond.

- K[PtCl3(C2H4)]: In this compound, the ethylene ligand is bonded to the platinum atom through a π-bond. The presence of the π-bond indicates that this is an organometallic compound.

- [Fe(η5-C5H5)2]: This compound contains two cyclopentadienyl ligands bonded to an iron atom. The bonds between the cyclopentadienyl ligands and the iron atom are π-bonds.

Therefore, the correct options that represent π-bonded organometallic compounds are A, C, and D. These compounds exhibit π-bonding between the metal atom and the organic ligands, making them organometallic in nature.
