2-Chloropropane Based on what you have learned so far, predict the more stable product in the reaction of CH2=CH-CH2-CH3 with HBr (circle the arrow for the step that leads to the predicted product), then calculate the energies of intermediates and products. Reactions normally go through the most stable intermediate, irrespective of the stability of the product. Circle the product you would get based on the stability of the intermediate.
