Question

The catalytic activity of the transition metals and their compound is ascribed 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.

Answer 1

Correct Answer - 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.
