Consider the following reaction HCI If the reaction is carried out at 40°C, what is the major product? Draw the product and the mechanistic step that leads to the product. If the reaction is carried out at 0°C, what is the major product? Draw the product and the mechanistic step that leads to the product. (hint: consider polarization of the carbocation intermediate to determine the product).

Draw the major product(s) of the following reaction.

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.

Complete the mechanism for the keto-enol tautomerization shown using bonds, charges, nonbonding electron pairs, and curved arrows (forward reaction only). Do not delete any pre-drawn bonds, charges, or lone pairs. If you accidentally delete a vital part of the structure, click the undo button in the lower left. Step 1: keto form. Draw curved arrows. Step 2: complete the structure, then add curved arrows. Select Draw Rings More Erase Select Draw Rings More Erase H H - H :0: :0: :o: 1L :o:

Draw the strcutres of the missing reactants, intermediates, or products in the following mechanisms. Include all lone pairs.

Draw the major product(s) of the following reaction.

For the following reactions, fill in the boxes with the predominant product or products. You must indicate stereochemistry with wedges and dashes. If a racemic mixture is created, you must write "racemic" under the structures.

Draw the structure of the major organic product(s) for the following reaction. Indicate the stereochemistry for each reaction when appropriate. ********* C1 H KOH heat

Question 11

Draw the structure of the intermediate that forms in the first step of the reaction mechanism and the product.  The electrophilic addition reaction in question 3, proceeds through two intermediates and three discrete mechanism steps. Using curved arrow formalism, draw the reaction mechanism for the transformation in question 3 with Br2 and H2O.
