Vedclass · Answer

(A) The reaction involves the electrophilic addition of $HBr$ to $3-bromocyclohexene$.First,the protonation of the double bond occurs to form a stable carbocation at the $C-3$ position relative to the existing $Br$ atom.Since the reaction proceeds through a classical carbocation,the $Br^-$ ion can attack the carbocation from either face.However,due to steric hindrance and the geometry of the cyclohexane ring,the attack of the bromide ion results in the formation of $trans-1,3-dibromocyclohexane$ as the major product,as shown in the reaction mechanism.

Surprisingly,the reaction shown below goes through a classical carbocation. What is the major product of this reaction?
