Chemistry Question on Redox Reactions
Cr2+ is stronger reducing agent than Fe2+ because:
A
it has exactly full filled configuration
B
d3 configuration of Cr3+ is more stable than d5 configuration of Fe3+ in aqueous solution
C
oxidises easily to form Cr4+
D
Fe2+ is quite stable and does not oxidise
Answer
d3 configuration of Cr3+ is more stable than d5 configuration of Fe3+ in aqueous solution
Explanation
Solution
The correct option is (B) : d3 configuration of Cr3+ is more stable than d5 configuration of Fe3+ in aqueous solution
