Chemistry Question on coordination compounds
Which one of the following characteristics of the transition metals is associated with their catalytic activity:
A
High enthalpy of atomization
B
Paramagnetic behaviour
C
Colour of hydrated ions
D
Variable oxidation states
Answer
Variable oxidation states
Explanation
Solution
The catalytic activity of transition metals is often associated with their ability to exhibit variable oxidation states. This variability in oxidation states allows them to readily undergo redox reactions, which are a common feature of many catalytic processes. Transition metals can easily donate and accept electrons in their various oxidation states, making them effective catalysts in many chemical reactions.
So, the correct option is (D): Variable oxidation states.
