Question

explain dehydrohalogenation of 2bromo butane​

Answer 1

Answer:

f two alkenes may be formed due to dehydrohalogenation of a haloalkane, the one which is most substituted is the main product. Example 3. For example, dehydrohalogenation of 2-bromobutane gives, The order of reactivity of haloalkanes in dehydrohalogenation is, Tertiary > Secondary > Primary

Explanation:

Answer 2

Answer:

Explanation:Explanation: Haloalkanes give alkene when heated with alcoholic potassium hydroxide , Dehydrohalogenation reaction. The formation of more substituted alkene will be favored. So, when we 2- bromobutane is heated with alcoholic KOH we will get major yield of But-2ene and minor yeild of But-1-ene. 3.9.
