Vedclass · Answer

(B) The reaction involves the acid-catalyzed isomerization of $But-1-ene$. Protonation of $CH_2=CH-CH_2-CH_3$ follows Markovnikov's rule to give a secondary carbocation,$CH_3-C^{+}H-CH_2-CH_3$. Loss of a proton from the $C3$ carbon leads to the formation of the more stable alkene,$But-2-ene$ $(CH_3-CH=CH-CH_3)$,according to Saytzeff's rule. $CH_2=CH-CH_2-CH_3$ $\xrightarrow{H^{+}} CH_3-C^{+}H-CH_2-CH_3$ $\xrightarrow{-H^{+}} CH_3-CH=CH-CH_3$.

$CH_2=CH-CH_2-CH_3 \xrightarrow{H^{+}/\Delta} \text{Major product}$. Identify the major product in the above reaction.
