Question
Chemistry Question on d block elements
Transition metals make the most efficient catalysts because of their ability to
A
adopt multiple oxidation states and to form complexes
B
form coloured ions
C
show paramagnetism due to unpaired electrons
D
form a large number of oxides
Answer
adopt multiple oxidation states and to form complexes
Explanation
Solution
Transition metals have partially filled d- orbitals so they can easily withdraw the electrons from the reagents or give electrons to them depending on the nature of the reaction. They also have a tendency to show large no. of oxidation states and the ability to form complexes which makes them a good catalyst.
