Vedclass · Answer

(B) disproportionation reaction is a type of redox reaction where the same element is simultaneously oxidized and reduced.$F_2$ is the most electronegative element and cannot exhibit a positive oxidation state,so it cannot undergo disproportionation.$Cl_2$,$Br_2$,and $I_2$ can exist in various positive oxidation states (such as $+1, +3, +5, +7$) and thus undergo disproportionation in alkaline media.Therefore,$Cl_2$,$Br_2$,and $I_2$ can undergo disproportionation reactions.

Among the following halogens $F_2$,$Cl_2$,$Br_2$ and $I_2$,which can undergo disproportionation reaction?
