Chemistry Question on GROUP 14 ELEMENTS
Identify the correct statement about the oxidation states of group 14 elements
A
Carbon and Silicon mostly exhibit +4 oxidation state
B
Tin in +2 oxidation state is a reducing agent
C
Lead in +2 oxidation state is a reducing agent
D
The order of stability of +2 oxidation state follow the sequence Ge<Sn<Pb
Answer
Lead in +2 oxidation state is a reducing agent
Explanation
Solution
The correct option is: (C): Lead in +2 oxidation state is a reducing agent.
The member of group 14 possesses a set of 4 valence electrons, leading to an inherent oxidation state of +4. Nevertheless, due to the inert pair phenomenon, the lower oxidation state gains stability while the higher oxidation state loses stability. Consequently, this group showcases oxidation states of both +4 and +2.
