Which of the following statements are correct about this reaction?
(i) The given reaction follows mechanism.
(ii) (b) and (d) have opposite configuration.
(iii) (b) and (d) have same configuration.
(iv) The given reaction follows mechanism.
(i), (ii) In the given reaction, alkyl halide is primary in nature. Here, a transition state is observed in which one bond is broken and one bond is formed simultaneously i.e., in one step. So, it follows the mechanism.
In this mechanism, the nucleophile attacks the carbon at to the leaving group. So the reactant and product have opposite configurations.
