Practice Problem 6‐4 – Answer Draw all important contributing structures for the following allylic carbocations; then rank the structures in order of relative contributions to each resonance hybrid. (a) (b) (c) Practice Problem 6‐5 – Answer Predict the structure of the major product formed by 1,2‐addition of HCl to 2‐methyl‐1,3‐butadiene (isoprene). Practice Problem 6‐6 – Answer Predict the structure of the major product formed by 1,4‐addition of HCl to isoprene. Practice Problem 6‐7 – Answer Predict the structure of the major 1,2‐addition product formed by reaction of one mole of Br2 with isoprene. Also predict the structure of the major 1,4‐addition product formed under these conditions. Practice Problem 6‐8 – Ans...
