Question: Complete The Drawing Of The Product Of The Diels?Alder Reaction, Ignoring Stereochemistry. START WITH WHAT IS ALREADY IN THE GRID Please.Learn the specifics of the Diels-Alder mechanism. Overview: The Diels-Alder reaction combines a diene (a molecule with two alternating double bonds) and a dienophile (an alkene) to make rings and bicyclic compounds.The three double bonds in the two starting materials are converted into two new single bonds and one new double bond.Complete the drawing of the product of the Diels-Alder reaction, ignoring stereochemistry. The Diels- Alder reaction between butadiene and dimethyl maleatc yields a ring structure, as shown in the product below Complete the structure by drawing any missing bonds and indicating the stereochemistry of the new stereocenters.A few more points about the stereochemistry of the Diels-Alder reaction depending on the structure of the diene and the dienophile. First, remember that if there are two groups on the dienophile, the product will have them cis or trans exactly as they initially appear in the dienophile. This indicates that Diels-Alder is a stereospecific reaction:3) (20 points) Draw all the products formed in the following Diels-Alder reactions. Clearly indicate the stereochemistry in the products. If a racemic mixture of products is formed you only need to draw one enantiomer. Indicate the racemic mixture with a "(+/-)" sign. (a) CH3 CN H H CN + CH3 Diels-Alder CH3 CN CN CH3 CN CN CH3 CH3

Complete the drawing of the product of the Diels-Alder
Mechanism of the Diels-Alder Reaction. Overlap of the molecular orbitals (MOs) is required: Overlap between the highest occupied MO of the diene (HOMO) and the lowest unoccupied MO of the dienophile (LUMO) is thermally allowed in the Diels Alder Reaction, provided the orbitals are of similar energy....Abstract For the following experiment, a Diels-Alder reaction between maleic anhydride and anthracene was conducted. Reflux mechanism was used for the reaction to occur. To increase the speed of the reaction, xylene was used because of its high boiling point.After the reaction was complete, 1.08g of the off white product was obtained with a yield of 69.7%.Side Reactions: Anhydride product of Diels-Alder reaction could have possibly hydrated before extraction, causing it to be soluble in petroleum ether. The 1,3-butadiene could have evaporated before it had a chance to react with the maleic anhydride. Method of Purification: Conclusion: The purpose of this reaction was achieved.A) B) Complete the drawing of the product of the Diels-Alder reaction, ignoring stereochemistry.

Diels-Alder response is an instance of cycloaddition response. In which two different molecules containing π\rm\pi π bonds react with each other in a concerted means and a new cyclic compound is shaped.
The Diels-Alder reaction sometimes called [4+2]\left[ 4 + 2 \proper][4+2] cyclo-addition. In this response, two issues are vital, one is diene and every other is dienophile. The diene is a conjugated device and the dienophile may also be an alkene or an alkyne. The diene is an electron wealthy species and the dienophile is an electrophile (electron deficient species).
The diene must be in S-cis conformation. A lower in the electron density in dienophile will increase its reactivity against the reaction. It is a concerted reaction, this is, bond breaking and bond forming occurs simultaneously. The common mechanism of Diels-Alder reaction is as follows:
In the first step, marked the diene and dienophile.
