Question:
Metal carbonyls are stable due to
Metal carbonyls are stable due to
Updated On: Dec 26, 2023
- $\sigma$-back bonding
- synergic bonding
- either (a) or (b)
- neither (a) nor (b).
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The metal-carbon bond in metal carbonyls possesses both $\sigma$ and $\pi$-characters. The ligand to metal is $\sigma$-bond and metal to ligand is back bonding through $\pi$-dative bond. This unique synergic bonding provides stability to metal carbonyls.

Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
