3. 1,2-dimethyl-1,3-cyclohexadiene reacts with HCl to form up to four different products. HCI 4 possible products a. b. Give the structures for the four products. When the reaction is run at low temperature, two products are formed preferentially ldentify these two products. c. When the reaction temperature is increased, a single product is favored. Identify the major product under these reaction conditions
The addition of HBr to 1,3-butadiene in the presence of a catalytic amount of peroxides
The addition of HBr to 1,3-butadiene in the presence of a catalytic amount of peroxides gives the expected product from anti-Markovnikov addition of HBr to one of the double bonds (BrCH2CH2CH CHa) and another product as shown below. Propose mechanism that explains how this product could be formed via a free radical mechanism. (Note: An ionic mechanism for the addition of HBr is also a possible explanation for the formation of the product. This is not what I am looking for...

a. Compound 6 reacts with hydrogen bromide as shown in reaction (4) i. Draw the structures of the potential products which may be formed in this reaction (ignore any stereochemical isomers). (4 marks) ii. Using curly arrows, draw a mechanism for the formation of each of the potential products. ldentify the major product. Explain briefly why the major product you identified is favoured.

The following compound can be prepared by the addition of HBr to either of two alkenes, give their structures Start with the same two alkenes, would the products be different if DBr(D = deuterium) were used instead of HBr? Explain using a mechanism that outlines the tree steps of all organic chemical reactions. The reaction of alpha-pinene with H_2 in the presence o Pd/c produces A and not B. Why does product B not form?

Critical Thinking Questions 1. Draw the structure for the product from the reaction of 1,3-cyclohexadiene and maleic acid (cis-2-butenedioic acid). 2. What is the product expected from the reaction of 1,3-butadiene and 3-sulfolene? Why is this not a major concern as a by-product? Part B, the dimer dicyclopentadiene is a possible contaminant of cyclopentadi- ene. It is also a diene. Can dicyclopentadiene undergo reaction with cyclopentadi- ene? Can dicyclopentadiene act as a diene and undergo reaction with the anhydride 3....

4-chloro-2-methyl-2-pentene reacts with acetic acid (solvent), two substitution products are urmea, with the rearranged product predominating as shown in the diagram that follows. When small amounts of acetate ion are added to the reaction mixture, no increase in the rate is observed. Propose a mechanism that accounts for these results. Explain clearly why two products are formed (5 points) Minor Major

Orgo Lab experiment: Isomerization of Carvone 1. Carvone contains a ketone and two double bonds. However, when treated with the concentrated acid only one reacts to create the carbocation. Which alkene reacts to form the carbocation and why only the one? 2. After the carbocation rearranges an elimination occurs, the alkene formed is a trisubstituted instead of the tetrasubstituted alternative. Why is this odd and what is the driving force for this specific alkene formation? 3. Using the H NMR...
