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

A

their chemical reactivity

B

their magnetic behaviour

C

their unfilled d-orbitals

D

their ability to adopt multiple oxidation state and their complexing ability

Text Solution

Verified by Experts

The correct Answer is:
D
Trasition element on account of their variable (multiply) valrncy have the ability to from intermediate compounds readily, thus acting as good catalyasts. Hence, the catalytic activity of the transition metals and their compounds is described to their ability to adopt multiple oxidation state and their ability to from complexes.
