Question

Which of the following is not an example of disproportionation reaction?
a) Cl, + 2NaOH → NaCl + NaOCl + H2O b) PA + 3NaOH + 3H2O → PH2 + 3NaH PO,
c) 2NaOH + 2F2 → 2NaF + OF2 + H2O d) 2H2O2 → 2H2O + O2​

Answer 1

A disproportionation reaction is a reaction in which a substance is simultaneously oxidized and reduced, giving two different products.

In the reaction, MnO

2 +4HCl⟶MnCl

2+Cl 2+2H 2 O,MnO 2

​

 is reduced and HCl is oxidized. Hence, it is not an example of disproportionation reaction.
