please show work - POU TULLUT 13. (4 points) Predict the products of the following Diels-Alder reaction. Show the stereochemistry of the products clearly. 13. (point) Predict the products of the following Diels-Alder reaction. Show the 4 VH * 6. (4 points) Benzene has an UV absorption at 2max = 204 nm, and cresol (para-methylphenol) has a max = 280 nm. How do you account for this difference? Draw at least one resonance structure to support your answer. HC=CH HC...
3) Explain why the following compound does not act as a diene in a Diels-Alder reaction: (4 pts)
this the pre lab questions for The Diels - Alder Cycloaddition Reactio expirment please answer all the question If the Diels-Alder reaction is classified as a [4 + 2] cycloaddition reaction, how would you classify the cycloaddition reactions shown below? You are instructed to use 140 mg of cyclopentadiene (d = 0.80 g/mL). It is typically more convenient to measure out a volume of liquid. What volume of cyclopentadiene should be used? In the Diels-Alder reaction that you will be...

Give the compounds that you would use to make the following compound using a Diels- Alder reaction. Be sure to show stereochemistry (cis or trans) if needed. (8 points)
16.42 please I dont understand A and if you could show the resonance as well. thanks 16.41 The absorbance spectrum of 1,3-butadiene displays an absorp- tion in the UV region (Amax=217 nm), while the absorption spectrum of 1,2-butadiene does not display a similar absorption. Explain. 16.42 Predict the products for each of the following Diels-Alder reactions: O HOOO COOHD Hoocan MeO ON 16.43 Identify the reagents you would use to prepare each of the following compounds via a Diels-Alder reaction...

O 41 V1, V2 V1, V2, V3 O Y1, 42, 43, 44 Consider the planar conformation for each of the following structures; how many are aromatic? NH NH2 2 Ο Ο
Can you please write the structure of the Diels-Alder products you would expect to isolate from each of the following reactions and explain it step by step so that I can solve problems similar to these. Thank you so much. -- If there are arrows and/or tricks to remember when solving this type of problem, please include. Practice problems: Cyclobutadiene is an extremely unstable compound whose isolation is impossible even at the lowest temperatures routinely accessible in the organic laboratory....
