Draw mechanism reacting a 1,3-butadiene with ethene.
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
1,3-Butadiene undergoes an electrophilic addition with HBr. 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.
Draw the HOMO of 1,3-butadiene: H2C=CH─CH=CH2.
(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) (10 points) In the Diels-Alder experiment the 3-sulfolene was used and converted to 1,3-butadiene.

The decomposition of 1,3-butadiene represents a second order process. 2 1,3-butadiene - (2,2)-15-Cyclooctadiene Answer the following questions about the decomposition of 1,3-butadiene. Report all answers to three significant figures. 1. The initial concentration of 1,3-butadiene is 1.945x10-2 M, however after 1.63 h the concentration decreases to 7.780x10- M. Calculate the rate constant (in /M hr) for this process. Submit Answer Tries 0/5 2. If the initial concentration of 1,3-butadiene is 1.945x10M, calculate the concentration (in M) of 1,3- butadiene after...
