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...

Consider the reaction of 2-methyl-1,3-cyclohexadiene with HCI.
Consider the reaction of 2-methyl-1,3-cyclohexadiene with HCI. Assuming that the reaction takes place at a very low temperature: (a) draw the intermediate and product structures, Including any formal charges. (b) What is the major product of the reaction at very low temperatures? Both products are formed in equal amounts. The 1,2-addition product. The 1,4-addition product. (c) Is the reaction under rate control or equilibrium control under the conditions stated above? The reaction is under rate control (kinetic). The reaction is under equilibrium control (thermodynamic). Unable to determine.

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....

The primary (1) alcohol substituent on the 1,3-cyclohexadiene molecule shown below was transformed into the Tosylate using chlorotrimethylsilane to produce a super leaving group. Hydrogen sulfide, H2S is a good nucleophile for a substitution reaction. Propose a complete "arrow-pushing" mechanism, including intermediate structures for the formation of the three listed products, HS HS heat SH SH (The-OTs leaves. Initial (1°) carbocation is OK, because of resonance stabilization.)
