Lower the E° value (more negative), stronger is the reducing agent.

Q. Strongest reducing agent among the following is (i) Na++e−⟶Na(s)​E∘=−2⋅71V (ii) Al3+3e−⟶Al(s)​E∘=−1⋅66V (iii) F2 (g) ​+2e−⟶2F−E∘=+2⋅87V (iv) 2H2​O+2e−⟶H2(g)​+2OH(aq)−​E∘=−0.83V

Lower the E∘ value (more negative), stronger is the reducing agent.

Lower the $E^{\circ}$ value (more negative), stronger is the reducing agent.
