Given
$E_{{Cl}_{2} / {Cl}^{-}}^{o} = 1 .36 V, E_{{Cr}^{3 +} / Cr}^{o} = - 0 .74 V$
$E_{{Cr}_{2} O_{7}^{2 -} / {Cr}^{3 +}}^{o} = 1 .33 V, E_{{MnO}_{4}^{-} / {Mn}^{2 +}}^{o} = 1 .51 V .$
Among the following, the strongest reducing agent is:

Options:

Answer:

Solution:

According to the given data standard reduction potential of $Cr$ is lowest. Lower the standard reduction potential, stronger the reducing agent. Therfore $Cr$ is the strongest reducing agent.
