The literature paper reports that higher than expected yields (exceeding 100%) may be obtained for the epoxidation with mCPBA. How does this occur? Group of answer choices Acid catalyzed ring opening of epoxide followed by nucleophilic attack to yield a product that has a higher molecular weight than the epoxide. Base catalyzed polymerization Base catalyzed ring opening of epoxide followed by nucleophilic attack to yield a product that has a higher molecular weight than the epoxide. Acid catalyzed polymerization Violation of the law of conservation of matter
