$\mathrm{In} \mathrm{Fe}(\mathrm{CO}) \mathrm{s}$, the Fe-C bond possesses
$\mathrm{In} \mathrm{Fe}(\mathrm{CO}) \mathrm{s}$, the Fe-C bond possesses
\pi-character only
Both $\sigma$ and $\pi$ characters
lonic character
$\sigma$ -character only
Solution
there is $\mathrm{d} \pi-\mathrm{p} \pi$ metal to ligand back bonding in Fe-C bond of the organometallic compound
$\mathrm{Fe}(\mathrm{CO})_{5} .$ So it possesses both $\sigma$ and $\pi$ characters.
