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. ....

SOLVED PROBLEM 7-3 When the following compound is heated in methanol, several different products are formed. Propose mechanisms to account for the four products shown. CH-Br CH heat CH,OH -OCH; + -OCH PARTIAL SOLUTION With no strong base and a good ionizing solvent, we would expect a first-order reaction. But this is a primary alkyl halide, so ionization is difficult unless it rearranges. It might rearrange as it forms, but we'll imagine the cation forming then rearranging. H. Br: CH...
