Understand how Transition Elements and Coordination Chemistry underpin key technologies, life processes, and environmental solutions, reinforcing their importance as a core pillar of Inorganic Chemistry.
Q. In redox reactions, what happens to the oxidation state of a transition metal when it acts as a reducing agent?
A.
It increases
B.
It decreases
C.
It remains the same
D.
It becomes zero
Solution
When a transition metal acts as a reducing agent, it donates electrons, resulting in a decrease in its oxidation state.
Q. What type of bond is primarily formed between a transition metal and a ligand in coordination complexes?
A.
Ionic bond
B.
Covalent bond
C.
Metallic bond
D.
Coordinate covalent bond
Solution
In coordination complexes, the bond formed between a transition metal and a ligand is primarily a coordinate covalent bond, where the ligand donates a pair of electrons.
