Solution

The correct option is C $[F e {(C_{5} H_{5})}_{2}]$
Ferrocene is an organometallic compound with the formula Fe 2. The molecule consists of two cyclopentadienyl rings bound on opposite sides of a central iron atom. It is an orange solid with a camphor-like odor, that sublimes above room temperature, and is soluble in most organic solvents
