Lithium is the strongest reducing agent though it has highest ionisation enegy in its group. Which of the followinng factors is responsible for making Li the strongest reducing agent?

Options

A. Large heat of atomisation
B. Smaller size
C. Large sublimation energy
D. Large amount of hydration enthalpy

Answer

D

Explanation

Large amount of hydration energy makes it strongest reducing agent inspite of its highest ionisation enthalpy.
`M_((s)) underset("energy")overset("Sublimation")to M_((g)) underset("Energy")overset("Ionisation")to M_((g))^(+) underset("energy")overset("Hydration")to M_((aq))^(+)`
