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. HẠC-CH–CH2–CH, • HAC-CH-CH2-CH, Br Energy: Energy H C=C CH2CH3 + HBr...

Draw a structural formula for the more stable carbocation intermediate formed in the reaction shown CH3 H,C-CHCH CHCHH You do not have to consider stereochemistry. Do not include anionic counter-ions, e.g., I, in your answer. For cases in which carbocations of the same or similar stability are expected, draw all of the structures. Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate structures with + signs from the drop-down menu. ....
