Chemistry - Halogen Derivative Question with Solution | TestHub

${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}$ being a weaker nucleopbile, when used as a solvent in case of hindered $1^{\circ }$ halide, favours ${\mathrm{S}}_{\mathrm{N}}1$ mechanism while ${\mathrm{C}}_2{\mathrm{H}}_5{\mathrm{O}}^{-}$being a strong nucleophile in this reaction favours ${\mathrm{S}}_{\mathrm{N}}2$ mechanism.
