Question

Which one is the best reducing agent among alkali metals in aqueous solution?

• A. $Li$
• B. $Be$
• C. $B$
• D. None of these

Answer 1

The correct option is A $Li$

$Li$ is the best reducing agent among alkali metals in aqueous solution owing to the hydration enthalpy of $L{i}^{+}$. $L{i}^{+}$ has very high charge density and hence highly hydrated.
