Question

carbonyl complexes of metals from vanadium to cobalt follow which rule​

Answer 1

18 electron rule

Explanation:

The metal carbonyl compounds follow the EAN that means 18-electron rule.

Answer 2

Carbonyl complexes of metals from vanadium to cobalt follow the

18-electron rule​.

• Transition metals form bonds using ns, np, and (n-1)d orbitals. These orbitals are partially filled which makes the metal center both electron donor and acceptor.
• According to the 18-electron rule, also called the Effective Atomic Number (EAN) rule, transition metals contain 18 valence electrons which include the d electrons and the electrons from bounded ligands.
• Metals having 18 valence electrons attain the noble gas electronic configuration.
