Question

Which of the following reactions are disproportionation reaction ? A. 2 C u + → C u 2 + + C u 0 2 B. 3 K M n O 2 − 4 4 H + → 2 M n O − 4 + M n O 2 + 2 H 2 O 3 C. 2 K M n O 4 △ −−→ K 2 M n O 4 + M n O 2 + O 2 2 D. 2 M n O − 4 + 3 M n 2 + + 2 H 2 O → 5 M n O 2 + 4 H + 2 Select the correct answer from above options

Answer 1

Correct Answer - B Disproportionation reaction: The reaction in which same element/compound get oxidized and reduced simultaneously. (a). 2 C u + → C u 2 + + C u 0 2 (b). 3 M n O 2 − 4 4 H + → 2 M n O − 4 + M n O 2 + 2 H 2 O 3 (d). Option belongs to comproportionation reactioin.
