Question
The reaction of 1-butene with bromine, Br2, in aqueous solution gives primarily 1-bromo-2-butanol. Identify the nucleophilic species in the reaction.
Correct Answer
Option C is the correct answer.
Detailed Explanation
In halohydrin formation, Br2 forms a bromonium ion intermediate. Water (H2O) acts as the nucleophile, attacking the more substituted carbon of the bromonium ion to give the bromohydrin (1-bromo-2-butanol).
Hint
