- Addition of HCl to alkene X forms two alkyl halides Y and Z. (A) Label Y and Z as a kinetic or thermodynamic product and explain why. (B) Explain why the addition of HCl occurs at the exocyclic C=C, rather than the other C=Carrow_forwardWhat steps are needed to convert A to B?arrow_forwardDraw enol tautomer(s) for each compound.arrow_forward
- A is a toxin produced by the poisonous seaweed Chlorodesmis fastigiata. (a) Label each alkene that exhibits stereoisomerism as E or Z.arrow_forwardBromoetherification, the addition of the elements of Br and OR to adouble bond, is a common method for constructing rings containingoxygen atoms. This reaction has been used in the synthesis of thepolyether antibiotic monensin (Problem 18.34). Draw a stepwisemechanism for the following intramolecular bromoetherification reaction.arrow_forwardDraw the products (including stereochemistry) for each reaction.arrow_forward
