Wired Faculty App

Which of the following species, do not show disproportionation reaction and why?
ClO–, ClO2–, ClO3- and ClO4– 
Also write reaction for each of the species that disproportionates.

Answer

ClO- (hydrochlorite ion):

ClO4-1 (perchlorate ion) cannot show any disproportionation reaction. The oxidation state of Cl is ClO4- ion is +7. It is the maximum oxidation state which it can have. It is the maximum oxidation state which it can have. It can decrease the same by undergoing reduction and not increase it anymore hence ClO4- ion does not undergo disproportionation reactions.
