1)Chemistry students are taking an experimental course in organic chemistry at a public university. During an experiment involving conjugated dienes, some doubts arose when discussing the results obtained so far: (a) A student obtained two products from the reaction of 1,3-cyclohexadiene with Br2. His lab partner was surprised to get only one product from the reaction of 1,3 - cyclohexadiene with HBr. Explain these distinct results. (b) One student, seeing the discussion of colleagues, commented that she obtained two distinct products when reacting 1,3,5-hexatriene with HBr, with different yields just by changing the reaction temperature. Explain the results she obtained using reaction mechanism and based on kinetic and thermodynamic control involving conjugated dienes.

In 4+2 cycloaddition, ENDO stereochemistry is preferred because: endo stereochemistry allows the diene to adopt s-cis conformation. endo stereochemistry results in less steric hindrance. the transition state leading to endo stereochemistry is higher energy. it allows for additional π to π overlap between the diene and the dienophile.
