chirality centers.
Why is trans trans 1,4-Diphenyl-1,3-Butadiene thermodynamically more stable than cis trans 1,4-Diphenyl-1,3-Butadiene?
6. The polymerization of butadiene produces three isomeric polymers, but the polymerization of isoprene - 2-methyl-1,3-butadiene produces four possible isomers by the same mechanism 1,3- butadiene (no unusual mechanism). Draw the four possible isomeric polymers. Isoprene

Complete the steps in the mechanism to produce the product
shown1) Add curved arrows for the first step. 2) Draw both the organic and inorganic intermediate species. Include all nonbonding electrons and charges. Draw a curved arrow to convert the intermediate into the product shown.
(10 points) In the Diels-Alder experiment the 3-sulfolene was used and converted to 1,3-butadiene. Why didn't we just start with 1,3-butadiene and what diene conformation is best for this experiment? (Write the two step mechanism for this reaction)
