MHT CET Chemistry question

The catalytic activity of the transition metals and their compounds is described to

(A)their chemical reactivity
(B)their magnetic behavior
(C)their unfilled d-orbitals
(D)their ability to adopt multiple oxidation states and their complexing abilityCorrect

Answer: (D)

Solution

Transition metals act as catalysts because they can adopt multiple oxidation states and form complexes (intermediates) so that they can provide alternative reaction
