Question

Which of the following is not an example of disproportionation reaction?

• A. $4ClO_{3}^{-} \rightarrow Cl^{-} + 3ClO_{4}^{-}$
• B. $2H_{2}O_{2} \rightarrow 2H_{2}O + O_{2}$
• C. $2NO_{2} + 2OH^{-} \rightarrow NO_{2}^{-} + NO_{3}^{-} + H_{2}O$
• D. $TiCl_{4} + 2Mg \rightarrow Ti + 2MgCl_{2}$

Answer 1

Answer: (D)

$TiCl_{4} + 2Mg \rightarrow Ti + 2MgCl_{2}$

Answer 2

:

$\overset{+ 4}{TiCl_{4}} + \overset{0}{2Mg} \rightarrow \overset{0}{Ti} + 2\overset{+ 2}{Mg}Cl_{2}$ Displacement reactio,
