Which of the following is not an intermolecular redox reaction?A. `MgCO_(3) rarr MgO + CO_(2)`B. `O_(2) + 3H_(2) rarr 2H_(3)O^(+)`C. `K + H_(2)O rarr KOH + ((1)/(2))H_(2)`D. `MnBr_(3) rarr MnBr_(2) + ((1)/(2)) Br_(2)` |
Answer» Correct Answer - A Intermolecular redox reactions and redox reactions are same. `overset(+2)(M)g overset(+4)(C) overset(-2)(O_(3)) rarr overset(+2)(M)g overset(-2)(O) + overset(+4)(C) overset(-2)(O_(2))` As there is no change in oxidation number of atoms, therefore, this reaction is not an intermolecular redox reaction. |
