Vedclass · Answer

(D) To obtain the maximum percentage of the terminal alkene (Hoffman product) in a dehydrohalogenation reaction,a bulky base is required. Steric hindrance prevents the base from abstracting a proton from the more substituted $\beta$-carbon,favoring the abstraction of a proton from the less substituted $\beta$-carbon. Among the given options,the potassium alkoxide derived from $3$-ethyl-$3$-pentanol,which is $(C_2H_5)_3CO^-K^+$,is the bulkiest base. Therefore,it will yield the highest percentage of the terminal alkene.

Which one of the following is used to obtain the maximum percentage of terminal alkene by dehydrohalogenation of $CH_3CH_2C(CH_3)_2Br$?
