Question

Li has the maximum value of ionisation potential among alkali metals i.e. Lithium has the minimum tendency to ionise to give $L{i}^{+}$ ion. Thus, lithium is

• A. Strongest reducing agent
• B. Poorest reducing agent
• C. Strongest oxidising agent
• D. Poorest oxidising agent

Answer 1

The correct option is A Strongest reducing agent

The ionisation potential value of Lithium is maximum among alkali metals i.e., its tendency to ionise to give $L{i}^{+}$ ions should be the minimum i.e., Li should be the poorest reducing agent. But, Lithium is the strongest reducing agent. This is due to the largest value of hydration energy of $L{i}^{+}$ ions.

Hence, option (a) is correct.
