- Why must dehydration reactions of alcohols be carried out under acid catalysis? O 1) the hydroxide group is a poor leaving group and must be protonated to 1) generate a better leaving group. 2) the hydroxide group is a great leaving group and does not need to be protonated to generate a better leaving group. O 3) the acid isn't necessary for the reaction. O4) None of these are correct answers.Consider the retrosynthetic sequence shown below. Part: 0/3 Part 1 of 3 OH Br ?
