Question

.30 + Which of the following examples does not represent disproportionation ? (A) MnO2 + 4HCI → MnCl2 + Cl2 + 2H2O (BY 2H,02 → 2H,0 + O2 (C) 4KCIO, +3KCIO4 + KCIE → (D) 3CP+6NaOH Nacī+ Nacioz + 3H,0​

Answer 1

Answer:

A) MnO₂ + 4HCI ⇒ MnCL₂ + CL₂ + 2H₂O

Explanation:

Disproportionation reaction is that reaction in which same substance undergoes oxidation as well as reduction to give two different products.

In  reaction, oxidation state of chlorine changes from -1 in HCl to 0 in Cl₂  

and -1 in MnCl₂   .Here chlorine undergoes only oxidation. So this is not disproportionation.
