two procedures:

1. a microscale cis-trans isomerization of an alkene

2. a miscroscale addition of bromine to fumaric acid

For each procedure:

a. predict which alkene will predominate at equilibrium (please explain)

b. predict the stereochemistry of the products formed if the addition of bromine to fumaric acid occurs via: syn addition, anti addition, and stereorandom addition

Thank You

Expert Solution

1. a microscale cis-trans isomerization of an alkene

2. a miscroscale addition of bromine to fumaric acid

Called anti addition,because the 2 bromines ends in an anti configuration

The mechanism must be a back-side attack of the nuclophile (Br -)

The mechanism for the meso-product (stereorandom addition) the Bromide can attack either carbon of the bromonium ion

Photochemical isomerization of Alkene: cis-1,2-dibenzoylethylene 6-38: What are some clues that tell you that you have made a different isomer product in this reaction? 6-39: Suggest a reason why the starting material (trans-1,4-diphenyl-2-butene-1,4-dione) should be recrystallized(or pure) prior to use ( NOTE: you did not perform the recrystallization, but were provided with the recrystallized material). 6-40:Cis-and trans-1,4-diphenyl-2-butene-1,4-dione are stereoisomers. What is the specific relationsip between the two of them? 6-41:Explain how this photochemical isomerizartion allows the production of the thermodynamically...

Below are isomers of 1,2-di(2-methylpropyl)cyclohexane in conformational structures. Two are cis and two trans. Indicate which is the more stable conformation for the cis and which for the trans, and indicate which of all the conformations is the most stable. If both conformations of the isomer are equally stable, select both. Select the mote stable conformation of cis-1,2-di(2-methylpropyl)cydohexane. Select the more stable conformation of trans-1,2-di(2-methy1propyl)cyclohexane. Select the most stable conformation overall.

3. Which is more stable, cis- or trans- 2-butene? Offer an explanation why? Hint: you might try measuring the distance between non-bonded pairs of hydrogens. You should also look at the molecules in space filling mode. The latter method is perhaps most revealing. The van der Waals radius for a hydrogen atom is ~1.20Å. 4. Is 2-methylpropene more or less stable than the isomers of 2-butene? Offer an explanation why placing two alkyl groups on the same carbon has a...
