Alec wanted to prepare to diene B to use in a subsequent Diels-Alder reaction. He thought he could prepare it via the reaction shown below. However, treatment of the diol (A) with acid yield either ketone (C) as the major product. H,SO, HO IPh Нeat Ph Ph OH B C a. Give a detail account of how you would determine whether product of the reaction was B or C. Assume that the only method available to you is FT-IR. You must give values for all features of all spectra. b. Provide a detail mechanism as to how compound B and C are formed under the reaction conditions. ..

6) The Diels-Alder reaction of anthracene (which is achiral) and maleic anhydride (also achiral) results in the formation of an achiral product. This is not always the case (where two achiral reactants form an achiral product). a) Propose a Diels-Alder reaction where two achiral starting materials result in the formation of a chiral product. b) Would this chiral product be a single enantiomer or a racemic mixture?
