Following is an example of a type of reaction known as a Diels-Alder reaction1,3-PentadieneEthylene3-Methylcyclohexene(a racemic mixture)The Diels-Alder reaction between a diene and an alkene is quite remarkable in that it isone of the few ways that chemists have to form two new carbon-carbon bonds in a singlereaction. Given what you know about the relative strengths of carbon-carbon sigma andpi bonds, would you predict the Diels-Alder reaction to be exothermic or endothermic?Explain your reasoning.

Considering the given example, the prediction is made as shown below,

Imagine that you used isoprene as diene – in that case you don’t have to worry about assigning endo vs exo. Draw the "endo" and "exo" products of the Diels-Alder reaction between isoprene and maleic anhydride, and explain why the distinction is irrelevant here.
Is the following true or false? To catalyse a Diels-Alder reaction a common approach involves the use of a Lewis acid capable of lowering the LUMO of the dienophile.
This is a Diels-Alder reaction between ethylene and cis-1,3-butadiene. For each cycloaddition product, draw in all hydrogen atoms, and write the molecular formula below.
Dimethyl azodicarboxylate takes part in a DielsAlder reaction as a dienophile. Write the structure of the cycloaddition product of this molecule with 1,2-dimethylenecyclohexane. Knowing that this compound is formed under mild conditions, explain what favors reactivity in a Diels-Alder reaction over diene and dienophile structures.
Draw the pi molecular orbital (MO) diagrams for cyclopentadiene and maleic anhydride, label whether the new bond formation in this Diels-Alder reaction will be suprafacial or antarafacial
Predict the product of the following Diels-Alder reaction. Make sure to indicate stereochemistry whereverapplicable.
Of the three 1,4-diphenyl-1,3-butadiene isomers (E,E or E,Z or Z,Z) indicate the most suitable diene that can be used as a reactant in a Diels-Alder reaction. Explain your choice.

Highlight the two new sigma carbon-carbon bonds that were formed in the Diels-Alderreaction.
Please answer both parts to the questions completely. I will rate the answer afterwards. For a diels-alder reaction between anthracene and maleic anhydride, are the exo and endo forms of product 9,10-dihydroanthracene-9,10-ɑ,β-succinic acid anhydride different stereoisomers or are they the same molecule? Explain your answer by drawing the molecule. Would it be favorable to get a 1,4-adduct of anthracene and maleic anhydride? Why or why not? If the 1,4-adduct of anthracene and maleic anhydride had formed, would it have different exo and endo isomers? Yes or no and why?
Give the structure(s) of the product(s) of each reaction. Indicate any relative stereochemistry, assuming that each of the Diels-Alder reactions will proceed with endo selectivity. If more than one product is formed, please indicate which one will be the major product or if they will be formed in equal amounts. If no reaction is expected to occur under the indicated conditions, then write "no reaction" or NR, and explain why you would expect nothing to occur. In all cases, equimolar amounts of both components/reagents are present unless indicated otherwise.
