  Which of the following statements are correct about this reaction ? (a) The given reaction follows S^2 mechanism. (b)(II) and (IV) have opposite configuration. (c) (II) and (IV) have same configuration. (d) The given reaction follows S^l mechanism.

Answer:

  (A, D) Since compound (II) is a 2° alkyl halide, therefore, a carbocation intermediate will be formed and the reaction proceeds through  mechanism. Thus, options (a) and (d) are correct.
