Chemistry - Halogen Derivative Question with Solution | TestHub

Since the reactant is a$3^{\mathrm{o}}$alkyl halide, so in the presence of$\mathrm{N}\mathrm{a}\mathrm{C}\mathrm{N},$it will follow E2 path rather than${\text{S}}_{\text{N}}\text{2,}$so path$\left(\mathrm{I}\mathrm{I}\right)$is not feasible.
The possible product by path$\left(\mathrm{I}\mathrm{I}\right)$is
