$1-$Methylcyclobutene

Vedclass · Answer

(B) The reaction involves the acid-catalyzed dehydration of cyclobutylmethanol. $1$. Protonation of the hydroxyl group occurs to form a good leaving group $(-OH_2^+)$. $2$. Loss of water generates a primary carbocation (cyclobutyl-methyl cation). $3$. This primary carbocation undergoes a ring expansion rearrangement to form a more stable five-membered ring (cyclopentyl cation). $4$. Loss of a proton from the cyclopentyl cation yields cyclopentene as the major product. Note: The provided options do not include cyclopentene. Among the given structures,if we assume the question implies a rearrangement leading to a more stable alkene,the most stable product formed from such rearrangements is typically cyclopentene.
