179 Haloalkanes and Haloarenes
If a 50:50 mixture of  A and B is obtained then the process is called
racemisation and the product is optically inactive, as one isomer will
rotate the plane polarised light in the direction opposite to another Now let us have a fresh look at SN1 and SN2 mechanisms by
taking examples of optically active alkyl halides In case of optically active alkyl halides, the product formed as a
result of SN2 mechanism has the inverted configuration as compared
to the reactant This is because the nucleophile attaches itself on the
side opposite to the one where the halogen atom is present
