10 Question (3 points) @ See page 920 Complete the mechanism for the intramolecular aldol reaction shown below. Add the missing curved arrow notation, lone pair electrons, and nonzero formal charges to all boxes. The reaction requires a base (e.g., NaOH) but we will ignore the Nat because it does not participate in the mechanism. Do not add any other reagents. :0— I Elcb Draw lone pairs, non-zero formal charges, and curved arrows to show how hydroxide reacts with the...
*Ignore the structures drawn in pencil. The purple lines indicate that they are incorrect. 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...
