        Sn1

              Sn2

    Sn1 is a unimolecular reaction

    Sn2 is a bimolecular reaction

    It follows a 1st order kinetic mechanism.

    It follows the 2nd order Kinetic mechanism.

    Sn1 involves two steps

    Sn2 is a single-step process

    In Sn1, the rate of reaction depends on the concentration of the substrate.

    In Sn2, the rate of reaction depends on the concentration of both the substrate and the nucleophile.

    In Sn1 as the leaving group leaves, the substrate forms a carbocation intermediate. 

    In Sn2, the reaction happens in a single transition state.

    Optically active substrate becomes optically inactive and half of the optically active substrate becomes similar.

    Sn2 involves inversion reaction.
