Vedclass · Answer

(A) The reaction of $1,3$-cyclohexadiene with $1 	ext{ mole}$ of $HBr$ is an electrophilic addition reaction.$H^+$ adds to one of the double bonds to form the most stable carbocation.In $1,3$-cyclohexadiene,the protonation of one double bond leads to an allylic carbocation,which is resonance-stabilized.$Br^-$ then attacks the carbocation.The major product formed is $3$-bromocyclohexene,as it is the kinetic product of the electrophilic addition to the conjugated diene system.

The major product of the reaction of $1,3$-cyclohexadiene with $1 \text{ mole}$ of $HBr$ is:
