COMEDK · Chemistry · 25. Haloalkanes and Haloarenes
For \(S_{N}\) I reaction, the order of reactivity of haloalkanes is
- A tertiary halide \( < \) secondary halide \( < \) primary halide
- B tertiary halide \( < \) secondary halide \(>\) primary halide
- C tertiary halide \(>\) secondary halide \(>\) primary halide
- D tertiary halide \(>\) secondary halide \( < \) primary halide
Answer & Solution
Correct Answer
(C) tertiary halide \(>\) secondary halide \(>\) primary halide
Step-by-step Solution
Detailed explanation
\(\mathrm{S}_{\mathrm{N}} 1\) reaction is two steps reaction in which carbocation is formed as an intermediate in step I (rate determining step). Greater the stability of carbocation, greater will be its ease of formation from alkylhalide and faster will be the rate of reaction.…
