alkene are undergoing the addition reactions and the
products are as follows here the double bond only reacts and forms
the products as follows
This is (+)-a-Pinene, widely produced in plants, repellant to insects. Give the product when (+)-a-Pinene is...
1. Give the major product of the following reactions, write N.R. if no reaction happens. Indicate the stereochemistry if necessary: 1. Give the major product of the following reactions, write N.R. if no reaction happens. Indicate the stereochemistry if necessary: CHCl3 KOC(CH3)3, (CH3)3COH 1. conc. HBr, heat 2. KOBU, HOBU ✓ 1. NaoMe, MeOH 2. BrCN 1. 1 eq. BH3, THE 2. H2O2, NaOH, H20 3. Hg(OAc)2, MeOH 4. NaBH4, NaOH, H20
3. Give the major product for the following reactions. Proper stereochemistry (shape, geometry) is required / chirality may be ignored. Watch out for carbocation rearrangement, and proper geometry like cis/trans. (Be sure to check your work by working out reaction mechanisms - practice, practice, practice!) a. 2-methyl-1-pentene + HBr b. 2-methyl-1-pentene + HBr/peroxide c. 3-methyl-1-pentene + H30+ d. 3-methyl-1-pentene + 1.
