Vedclass · Answer

(A) The dehydration of $1$-butanol $(CH_3CH_2CH_2CH_2OH)$ with concentrated $H_2SO_4$ proceeds via an $E1$ mechanism. First,the hydroxyl group is protonated to form a good leaving group,which leaves to form a primary carbocation $(CH_3CH_2CH_2CH_2^+)$. This primary carbocation undergoes a $1,2$-hydride shift to form a more stable secondary carbocation $(CH_3CH_2CH^+CH_3)$. Elimination of a proton from the secondary carbocation yields $2$-butene as the major product,which exists primarily as the more stable trans-$2$-butene isomer.

What is the major product obtained when $1$-butanol is heated with concentrated $H_2SO_4$?
