The catalytic behaviour shown by transition elements is mainly attributed to which of the following?

1. variable oxidation states
2. free surface valencies
3. complex formation ability
4. magnetic moment

Correct answer: variable oxidation states

Solution

Transition metals can adopt multiple oxidation states, allowing them to provide alternative low-energy reaction pathways by forming and breaking intermediate species.
