Given below are two statements:
Statement - I: High concentration of strong nucleophilic reagent with secondary alkyl halides which do not have bulky substituents will follow $\mathrm{S}_{\mathrm{N}}{ }^2$ mechanism.
Statement - II: A secondary alkyl halide when treated with a large excess of ethanol follows $\mathrm{S}_{\mathrm{N}}{ }^1$ mechanism.
In the light of the above statements, choose the most appropriate from the options given below:
Solution
<p>Statement - I: Rate of $$\mathrm{S}_{\mathrm{N}} 2 \propto[\mathrm{R}-\mathrm{X}]\left[\mathrm{Nu}^{-}\right]$$</p>
<p>$\mathrm{S}_{\mathrm{N}} 2$ reaction is favoured by high concentration of nucleophile $(\mathrm{Nu}^{-})$ & less crowding in the substrate molecule.</p>
<p>Statement - II: Solvolysis follows $\mathrm{S}_{\mathrm{N}} 1$ path.</p>
<p>Both are correct Statements.</p>
