Which of the following options is correct with respect to bonding in metal carbonyls?

Options

  1. AMetal carbonyls have no covalent or ionic bonding, but rather exhibit metallic bonding between metal atoms and
  2. Bπ bond is formed by the donation of a pair of electrons from the filled metal d orbital into the vacant anti-b
  3. CMetal carbonyls involve hydrogen bonding between metal atoms and carbonyl ligands (CO).
  4. DMetal carbonyls involve ionic bonding between metal atoms and carbonyl ligands (CO) with a complete transfer o

Correct answer

B. π bond is formed by the donation of a pair of electrons from the filled metal d orbital into the vacant anti-b

Step-by-step solution

Correct Option is : (B) π bond is formed by the donation of a pair of electrons from the filled metal d orbital into the vacant anti-bonding π* orbital (also known as back bonding of the carbonyl group)
