Question
Chemistry Question on Classical Idea Of Redox Reactions – Oxidation And Reduction Reactions
Low oxidation state of metals in their complexes are common when ligands :
A
Have good π-accepting character
B
Have good σ-donor character
C
Are having good π-donating ability
D
Are having poor σ-donating ability
Answer
Have good π-accepting character
Explanation
Solution
The correct answer is (A): Have good π-accepting character
Ligands like :CO, are sigma donor and π-acceptor and they make stronger bond with lower oxidation state metal ion, in this case back bonding is more effective.
