Question
In which one of the following sets all species show disproportionation reaction? (A) 7 2 CrO and MnO , ClO (B) 2 Mn and ClO , MnO (C) 4 ClO and MnO , ClO (D) 2 2 2 Cl and ClO , MnO , O Cr
Answer: B
💡 Solution & Explanation
Disproportionation reactions are a special type of redox reactions. One of the reactants in a disproportionation reaction always contains an element that can exist in at least three oxidation states. The element of reacting species is in intermediate oxidation state and simultaneously gets oxidised and reduced. Note: NTA answer is (2), but Reso ans. is (Bonus) MnO do not shows disproportionation reaction. | JEE MAIN-2021 | DATE : 31-08-2021 (SHIFT-2) | PAPER-1 | OFFICAL PAPER | CHEMISTRY PAGE # 7
