When are low oxidation states found in complex compounds of transition elements?

Options

  1. AWhen ligands have 𝛔-bonding character
  2. BWhen ligands have π-acceptor character
  3. CWhen ligands have 𝛅-orbital character
  4. DWhen ligands have f-orbital character

Correct answer

B. When ligands have π-acceptor character

Step-by-step solution

Low oxidation states are found when a complex compound has ligands capable of π-acceptor character in addition to the 𝛔-bonding.
