$E_{F{e^{2 + }}/Fe}^o\, = \, - \,0.44\,\,V\,;\,\,E_{Z{n^{2 + }}/Zn}^o\, = \, - \,0.76\,\,V\,;\,$
$E_{C{u^{ + 2}}/Cu}^o\, = \,0.34\,\,V$
Based on this data, which of the following is the strongest reducing agent ?
$C_2H_5-Br\overset{AgCN}{\rightarrow}A\overset{H_2/Ni}{\rightarrow}B$
Product $B$ is
Given that :
$F{e^{2 + }} + 2{e^ - } \to Fe;$ ${E^o}_{F{e^{2 + }}/Fe} = - 0.47\,V$
$F{e^{3 + }} + {e^ - } \to F{e^{2 + }};$ ${E^o}_{F{e^{3 + }}/F{e^{2 + }}} = + 0.77\,V$
