The catalytic activity of transition metals and their compounds is ascribed mainly to

A

Their chemical reactivity

B

their magnetic behaviour

C

their filled d-orbitals

D

their ability to adopt multiple oxidation state and their complexing ability.

Text Solution

Verified by Experts

The correct Answer is:
D
The catalytic property of transition metals is due to their tendency to form reaction intermediates with suitable reactants. These intermediates give reaction paths of lower activation energy of vacant orbitals or their tendency to form variable oxidation states.
