Question

Standard reduction potentials of the half reactions are given below :

{\mathrm{F}_2}\left( \mathrm{g} \right) + 2{e^ - } \to 2{\mathrm{F}^ - }\left( {aq} \right);{E^ \circ } = + 2.85\mathrm{V}

\mathrm{C}{\mathrm{l}_2}\left( \mathrm{g} \right) + 2{e^ - } \to 2\mathrm{C}{\mathrm{l}^ - }\left( {aq} \right);{E^ \circ } = + 1.36\mathrm{V}

\mathrm{B}{\mathrm{r}_2}\left( l \right) + 2{e^ - } \to 2\mathrm{B}{\mathrm{r}^ - }\left( {aq} \right);{E^ \circ } = + 1.06\mathrm{V}

{\mathrm{I}_2}\left( s \right) + 2{\mathrm{e}^ - } \to 2{\mathrm{I}^ - }\left( {aq} \right);{E^ \circ } = + 0.53V

The strongest oxidising and reducing agents respectively are :
