Vedclass · Answer

(D) The first step is the electrophilic addition of $HCl$ to the double bond of the cyclohexene ring. According to Markovnikov's rule,the $H^+$ adds to the carbon with more hydrogens,and $Cl^-$ adds to the other carbon,forming the chloro-substituted product $[A]$.In the second step,the reaction with $NaI$ in dry acetone is a Finkelstein reaction,which is an $S_N2$ substitution where the chlorine atom is replaced by an iodine atom to form the iodo-substituted product $[B]$.

Identify $A$ and $B$ in the chemical reaction.
