The rate of dehydrohalogenation of which one among the following is less ?
- A \(\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{Br}\)
- B \(\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{Cl}\)
- C \(\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2\)
Answer & Solution
Correct Answer
(B) \(\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{Cl}\)
Step-by-step Solution
Detailed explanation
Dehydrohalogenation reaction order is alkyl halide relative reactivity order is \(3^{\circ}>2^{\circ}>1^{\circ}\) Alkyl halide reactivity order is \(\mathrm{I}>\mathrm{Br}>\mathrm{Cl}>\mathrm{F}\) (in \(\beta\) elimination of \(\mathrm{F}\) is rarely used). When heated with…
