the first two questions are asking to do acid-catalyzed mechanism. the last one is mutliple choice question yl-Fall 2019 SO. Draw the mechanism for the acid-catalyzed hydration of 3.3-dimethy the final product in the box below In words: protonation water gives a pro rearrangement to a more stable tertiary carbocation. Then (1) capture deprotonation gives the major organic product. Four curved arrows total on of 3,3-dimethylcyclohexene. (Draw the intermediates in the blank bra otonation of the alkene gives a secondary...
