    A concerted reaction is a reaction in which 1) # covalent bonds broken + #covalent bonds formed > 1, 2) # steps = 1.

    eg. 1:

    concertedreaction1.png

    mechanism: The reaction is a nucleophilic aliphatic substitution occurring via SN2 mechanism.

    concertedreaction2.png

    # covalent bonds broken = 1
    # covalent bonds formed = 1
    # covalent bonds broken + # covalent bonds formed = 1 + 1 = 2
    # steps = 1

    Thus, the reaction is a concerted reaction.

    eg. 2:

    concertedreaction3.png

    mechanism: The reaction is an electrophilic addition.

    concertedreaction4.png

    # covalent bonds broken = 2
    # covalent bonds formed = 2
    # covalent bonds broken + # covalent bonds formed = 2 + 2 = 4
    # steps = 1

    Thus, the reaction is a concerted reaction.
