Vedclass · Answer

(C) The reaction involves the electrophilic addition of $HCl$ to the alkene. $1$. Protonation of the double bond occurs to form the most stable carbocation. $2$. The initial carbocation formed is a tertiary carbocation on the side chain. $3$. Since a five-membered ring is adjacent to the carbocation,a ring expansion occurs to form a more stable six-membered ring carbocation. $4$. Finally,the chloride ion $(Cl^-)$ attacks the carbocation to form the major product,which is $1$-chloro-$1,2$-dimethylcyclohexane.
