The ease of dehydrohalogenation of akyl halide with alcohloic KOH is

A

`3^(@)lt2^(@)lt1^(@)`

B

`3^(@)gt2^(@)gt1^(@)`

C

`3^(@)lt2^(@)gt1^(@)`

D

`3^(@)gt2^(@)lt1^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
Dehydrohalogenation of alkyl halide follows E2 mechanism. The reaction will be more favourable with the increasing stability of the resulting alkene. As the alkene obtained from `3^(@)` alkyl halide is more subsituted, it has a very high stability. The ease of dehydrohalogenation of alkyl halide is: `3^(@)gt2^(@)gt1^(@)`.
