- I need help distinguishing 2 vs 3 for sterochemistry of bicycloalkenes such as the one attachedDraw the carbocation you'd expect from the reaction of 2-chloro-3-methylbutane with AlCl3?You are required to synthesize 2-bromopentane from the reaction between an alkene with HBr. Which alkene, 1-pentene or 2-pentene, should you react with HBr in order to get 2-bromopentane? Give an explanation.
- Draw every stereoisomer for 1‑bromo‑2‑chloro‑1,2‑difluorocyclopentane. Use wedge‑and‑dash bonds for the substituent groups, and be sure that they are drawn on the outside of the ring, adjacent to each other. Clearly show stereochemistry by drawing the wedge‑and‑dashed bonds like the example. You should replace the X with the appropriate halide.Draw and name all stereoisomers of 3-chlorohepta-2,4-diene using the E-Z nomenclature.4-Chloro-2-pentene has a double bond that can have either the E or the Z configuration and a stereogenic center that can have either the R or the S configuration. How many stereoisomers arepossible altogether? Draw the structure of each, and group the pairs of enantiomers.
