23. As 5 points. Complete 10 of the 15 following reactions by providing the missing information: reactants products or reagents and conditions. When predicting products, you must include all products that will most likely form in an appreciable amount. When more than one product is likely, label the major and minor products. (Watch out for rearrangements). Where appropriate, indicate stereochemistry, as well as whether or not...
