If the bond length of CO bond in carbon monoxide is $1.128 \overset{˚}{A}$

, then what is the value of CO bond length in $Fe (CO)_{5}$ ?

Options:

Answer:

Solution:

The CO bond length in Fe(CO)₅ is longer than in free CO due to synergistic bonding. Metal-to-ligand $π$ -backbonding from Fe to CO's $π^{*}$ antibonding orbital weakens the C-O bond, increasing its length. Thus, $1.15 \overset{˚}{A}$ is the most appropriate value.
