What is the detailed reactin scheme for the transformation? Describe the purification procedure.
- give the reagents for parts a-pThe reaction of 2-ethyl-1-pentene with Br2, with H2 + Pd/C, or with R2BH/THF followed by aqueous HO- + H2O2 leads to a racemic mixture. Explain why a racemic mixture is obtained in each case.True or false? 2-bromo-2-methylpropane undergoes SN1 rather than SN2 because the nucleophile experiences steric hindrance, and a stable carbocation can be formed. When hydroxide ion reacts with 1-chloropropane the main product is 1-propanol.
