Question

Li has the maximum value of ionisation potential among alkali metals i.e. lithium has the minimum tendency to ionise to give Li⁺ ion. Thus, lithium is -

(A) Strongest reducing agent 

(B) Poorest reducing agent

(C) Strongest oxidising agent 

(D) Poorest oxidising agent

Answer 1

Correct option(A) Strongest reducing agent 

Explanation :

The ionisation potential value of Lithium is maximum among alkali metals i.e. its tendency to ionise to give Li⁺ 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 Li⁺ ions.
