Question

Identify disproportionation reaction.

• A. $CH_{4} + 2O_{2} \rightarrow CO_{2} + 2H_{2}O$
• B. $CH_{4} + 4Cl_{2} \rightarrow CCl_{4} + 4HCl$
• C. $2F_{2} + 2OH^{-} \rightarrow 2F^{-} + OF_{2} + H_{2}O$
• D. $2NO_{2} + 2OH^{-} \rightarrow NO_{2}^{-} + NO_{3}^{-} + H_{2}O$

Answer 1

Answer: (D)

$2NO_{2} + 2OH^{-} \rightarrow NO_{2}^{-} + NO_{3}^{-} + H_{2}O$

Answer 2

: Disproportionation reaction is a special type of redox reaction in which an element in one oxidation state is simultaneously oxidised and reduced.
