Question

Li+Li+ has greatest reducing nature. True or false :

• A. True
• B. False

Answer 1

The correct option is A True

It's the anomalous behaviour of Lithium because of its small size and high nuclear charge. Lithium exerts the greatest polarizing effect out of all the alkali metals on negative ion. It is the dissoloution of the substance in water by absorbing water molecule by weak valency forces. Smaller the cation, greater is the degree of hydration. Alkali metals easily lose 1 electron therefore have high values of "oxidising potential" which means high tendency to get oxidised. Hence, powerful reducing nature in aqueous medium. It is a fact that $L{i}^{+}$ has greatest reducing nature in aqueous medium due to maximum hydration energy for $L{i}^{+}$ ion.
