Diels–Alder reaction of a monosubstituted diene (such as CH2=CH–CH=CHOCH3) with a monosubstituted dienophile (such as CH2=CHCHO)gives a mixture of products, but the 1,2-disubstituted product oftenpredominates. Draw the resonance hybrid for each reactant, and use thecharge distribution of the hybrids to explain why the 1,2-disubstitutedproduct is the major product.

Exp3: Diels-Alder reaction   Why does cyclopentadiene regularly form a dimer? How to break the dimer into monomers? Does the diene in this reaction act as the nucleophile or the electrophile? Is the maleic anhydride a nucleophile or an electrophile in this reaction? Explain your reasoning.

Complete the following Diels-Alder reaction by drawing a structure for the product formed.   Consider the resonance in the diene and dienophile and draw partial charges at correct positions.  That will help you in drawing the correct product.

Kk.41. please give the diene and dieneophile for these Diels-Alder products

Rank the following dienes in order of their reactivity in standard Diels-Alder reactions (1= most reactive, 4= least reactive). Be sure to briefly explain your choices.

A2 What is the inverse electron demand Diels–Alder reaction? Please pick a pair of a diene and a dienophile from the following dienes and dienophile that will undergo this type of reaction. Please show how this reaction works using Frontier Molecular Orbitals. What is the reaction product?

In the beginning of this video https://www.youtube.com/watch?v=9Ng6Zv9oLzk, what reason is given on why the dienophile likes the diene?

The following excerpt is a commonly used lab procedure for a Diels-Alder reaction. Provide three specific reasons why the one here would not be classified as a green chemistry option compared to ours. Be sure to reference and explain the principles of green chemistry to support your response. excerpt- Place 2 g of maleic anhydride in a 50-mL Erlenmeyer flask and dissolve it in 8 mL of ethyl acetate by warming on a hot plate. Add 8 mL of hexane or petroleum ether, and then cool the solution in an ice bath. Obtain 2 mL freshly cracked cyclopentadiene and add it to the maleic anhydride solution. Swirl to mix. Wait until the product crystallizes from solution, then heat it on the hot plate to redissolve, and allow it to recrystallize. Collect the product by suction filtration, and record the melting point, weight, and percentage yield.

Assign the stereochemical configuration (E or Z) for the alkene below. Show your work, indicating clearly which groups are assigned high priority (e.g., through assigning the groups numbers, circling only the high priority groups, or labeling groups as high or low).
