    A dextro-rotatory optically active alkyl halide undergoes hydrolysis by \[{{S}_{N}}2\] mechanism. The resulting alcohol is

    A)  dextrorotatory

    B)  laevorotatory

    C)  optically inactive due to racemization

    D)  may be dextro or laevorotatory

    Correct Answer: D

    Solution :

                    \[{{S}_{N}}2\] reactions occur with inversion of configuration. Therefore, an optically active reactant gives an optically active product whose sign of rotation cannot be predicted i.e. option  is correct.
