- Addition of HCl to alkene X forms two alkyl halides Y and Z. Explain why addition of HCl occurs at the indicated C=C (called anexocyclic double bond), rather than the other C=C (called anendocyclic double bond).arrow_forwardAlkene A can be isomerized to isocomene, a natural product isolated from goldenrod, by treatment with TsOH. Draw a stepwise mechanism for this conversion. (Hint: Look for a carbocation rearrangement.)arrow_forwardWhich reactions are stereoselective?arrow_forward
