Question

    How many electrons are involved in the oxidation by

    KMnO4 in basic medium
    A 3 Correct Answer Incorrect Answer
    B 1 Correct Answer Incorrect Answer
    C 4 Correct Answer Incorrect Answer
    D 2 Correct Answer Incorrect Answer

    Solution

    In alkaline medium,  KMnO4KMnO4  acts as an oxidising agent as follows  MNO−4+2H2O+3e−→MnO2+MNO4−+2H2O+3e−→MnO2+OH−OH− Thus three electrons per molecule of are involved.
