Standard reduction potential (SRP) of fluorine is highest. Comment.

Standard potential for the reaction, ${\mathrm{F}}_2+e^{-} \to 2\stackrel{-}{\mathrm{F}}$ is highest, +2.87 V.

This is because, fluoride is the easiest formed anion from its element and hydration enthalpy is highest for fluoride Highest SRP suggests that fluorine is the best oxidant.
