JEE MAIN - Chemistry (2024 - 30th January Evening Shift - No. 10)
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:
Explanation
Statement - I: Rate of $$\mathrm{S}_{\mathrm{N}} 2 \propto[\mathrm{R}-\mathrm{X}]\left[\mathrm{Nu}^{-}\right]$$
$$\mathrm{S}_{\mathrm{N}} 2$$ reaction is favoured by high concentration of nucleophile $$(\mathrm{Nu}^{-})$$ & less crowding in the substrate molecule.
Statement - II: Solvolysis follows $$\mathrm{S}_{\mathrm{N}} 1$$ path.
Both are correct Statements.
