उत्तर
(i) The given reaction follows SN2 mechanism.
(ii) (b) and (d) have opposite configuration.
Explanation:
In the given reaction, alkyl halide is primary in nature. Here, a transitory state is observed in which one bond is broken and one bond is formed synchronously he., in one step. So, it follows SN2 mechanism.
In this mechanism, nucleophile attacks the carbon at 180° to the leaving group. So the reactant and product have opposite configuration.
