1. Intramolecular bromine and double elimination

Predict the result of the following reactions:

2. Cycloalkenes and the meso form

Explain why the reaction of cycloalkenes such as cyclobutene, cyclopentene or cyclohexene with Br₂ never gives a meso form, but a racemic mixture.

3. Halohydrins

Give the product of the reaction of propene with Br₂ in water and explain its regiochemistry.
