NEET Chemistry The s-Block Elements Questions Solved

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, in aq. solution lithium is-

(A) Strongest reducing agent                       

(B) Poorest reducing agent

(C) Strongest oxidising agent                       

(D) Poorest oxidising agent

(A). 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 in aq. solution. This is due to the largest value of hydration energy of Li+ ions.
