Draw the more stable carbocation for each of the molecules below. Assume they are undergoing an SN1/E1 reaction. H₂C H3C CH3 CH3 CH3 Br CH3 Br

Draw the most stable resonance form for the intermediate in the following electrophilic substitution reaction. CH3 CH3 H3PO4 HO, + H3C CH3 HO HO First stage in synthesis of the epoxy and polycarbonate ingredient bisphenol-A You do not have to consider stereochemistry. Include all valence lone pairs in your answer. In cases where there is more than one answer, just draw one.
