A student allowed an alcohol, 4-penten-1-ol, to react with Br₂, expecting to observe a simple addition of Br₂ to the double bond. Instead, she isolated a compound X that proved to have the formula C₅H₉OBr. The reaction mixture from which X was isolated was very acidic.
Using mechanistic reasoning, including the curved-arrow notation, propose a structure for compound X. Show your logic at every step of the way! Your answer should explain why the reaction mixture became acidic.
