For the following reaction, draw all of t

Draw all intermediates and show all electron-pushing.

Acetal product formation requires an acid catalyst in the second step, but NOT in the first step. True or False?

Which are the major products on step two and three?

3. Does it matter what order you mix the reactants together in? If so, what is the correct order? 4. During the reaction, when do you start the timer? 5. How will you know when to stop the timer?

a) Draw a detailed mechanism for the reaction and show the structures of the endo and exo products.b) Label the endo and exo product in part a. c) Which transition state is lower in energy, the one leading to the exo product or the one leading to the endo product? d) Which product do you expect to be more stable (the exo or the endo product) and why? Using your answers to part c and d, draw the reaction co-ordinate diagram for the Diels-Alder reaction shown above. Which product do you expect to be favored at high temperatures, and which product at low temperatures (which product is the kinetic product and which one the thermodynamic product)?

Curved arrows are used to illustrate the flow of electrons. Use the reaction conditions provided and follow the arrows to draw the first intermediate formed in this reaction and the final product. Include all lone pairs and charges as appropriate. Ignore inorganic byproducts. Jo ✓:0: ď CH3 -CCH3 Draw Intermediate Q Problem 1

HO Cro3 H2S04 Edit Click on the drawing box above to activate the MarvinSketch drawing tool and then draw your answer to this question. If there is no reaction, then check the "no reaction" box below. no reaction

Draw the major product for the oxidation reaction. Then, draw the proper FULL electron-pushing mechanism for the reaction, including ALL intermediates (with formal charges) and electron-pushing arrows. Label the electrophile and nucleophile in each step.

Draw both combinations of alkoxide and alkyl iodide that are commonly used to try and form the product shown. Circle the pair of reactants that will give the best yield of the products and explain why the other pairs has impaired or no formation of the intended product.
