- DNickel carbonyl
✓
Answer
Correct option: B.
Ferrocene
b
(b)The complexes, in which, the metal and ligand form a bond that involves the $\pi - $electrons of the ligand are know as $\pi - $complexes e.g. Ferrocene
$Fe$${({\eta ^5} - {C_5}{H_5})_2},$ zeise’s salt $K[PtC{l_3}({\eta ^2} - {C_2}{H_4})]$.
