Chemistry - Halogen Derivative Question with Solution | TestHub

The more is the stability of intermediate carbonium ion, the more is the chance of ${\mathrm{S}}_{\mathrm{N}}1$ mechanism. The intermediates obtained will be ${\mathrm{Ph}}^{+}\mathrm{C}{\mathrm{H}}_2(\mathrm{i}),\mathrm{Ph}\mathrm{CH}-\mathrm{Me}(\mathrm{ii})$ $\mathrm{Ph}\mathrm{C}-{\mathrm{Me}}_2($ iii) $,\mathrm{Ph}{\mathrm{C}}^{+}\mathrm{MePh}$ (iv) The stabilty is of the order iv $>\mathrm{iii}>\mathrm{ii}>\mathrm{i}$
