Which of the following statements are correct about this reaction?

(i) The given reaction follows S_{N}2 mechanism.

(ii) (b) and (d) have opposite configuration.

(iii) (b) and (d) have same configuration.

(iv) The given reaction follows S_{N}1 mechanism.

Answers (1)

(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 S_{N}2 mechanism.

In this mechanism, the nucleophile attacks the carbon at 180^{\circ} to the leaving group. So the reactant and product have opposite configurations.
