Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding reducing agents.
A strong reducing agent is one which readily loses electrons.
Step 2: Comparing standard reduction potentials.
Lithium has the most negative standard reduction potential among the given metals.
Step 3: Hydration energy factor.
Although lithium has high ionization energy, its very high hydration energy makes it the strongest reducing agent in aqueous solution.
Step 4: Conclusion.
Thus, lithium is the strongest reducing agent.
