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?

Which of the following alkenes would yield an alkyne upon addition of Br2, followed by reaction with more than two molar equivalents of NaNH2?
Chap 8 - Addition Reactions to Alkenes A reaction is regioselective when two or more constitutional isomers might be expected to reasonably form as products, but one of them predominates. tert-butyl chloride 100 iso-butyl chloride There are degrees of regioselectivity ranging from no regioselectivity to completely regioselective. The top example is a completely regioselective reaction. (reason: 3° carbocation vs 1° carbocation). The greater the differences in the AG" value between two different carbocation pathways, the more regioselective the reaction will...
