Q. Standard reduction potentials of the half reactions are given below :
$ F_{2(g)} + 2e^- \rightarrow 2F^{-}_{(aq)} ; E^{\circ} = + 2.85 \, V $
$ Cl_{2(g)} + 2e^- \rightarrow 2Cl^{-}_{(aq)}; E^{\circ} = + 1.36 \, V $
$Br_{2(l)} + 2e^- \rightarrow 2Br^{-}_{(aq) } ; E^{\circ} = + 1.06 \, V$
$I_{2(g)} + e^- \rightarrow 2I^{-}_{(aq)} ; E^{\circ} = + 0.53 \, V $
The strongest oxidizing and reducing agents respectively are -

Solution:

All are SRP
I
Br
Cl
F
So Best $O.A. \to F_2$
Best $R.A. \to I^{-}$
