$CH_3-CH=CH-CH_3$

Vedclass · Answer

(B) The acid-catalyzed dehydration of butan-$1$-ol $(CH_3-CH_2-CH_2-CH_2OH)$ involves the formation of a primary carbocation,which undergoes a $1,2$-hydride shift to form a more stable secondary carbocation $(CH_3-CH^+-CH_2-CH_3)$.Elimination of a proton from this secondary carbocation yields but-$2$-ene $(CH_3-CH=CH-CH_3)$ as the major product,following Zaitsev's rule,as it is more substituted and thus more stable than but-$1$-ene $(CH_3-CH_2-CH=CH_2)$.

Predict the major product of acid-catalyzed dehydration of butan-$1$-ol.
