Bromine-ethene addition reaction basics Steps:

• Identify the reaction as electrophilic addition where Br2 adds across the C=C double bond of ethene.
• Recall that the mechanism involves a bromonium ion intermediate, leading to anti addition.
• Note the product is 1,2-dibromoethane, a colorless compound from orange Br2.
• Determine correct statements based on reaction type, stereochemistry, and conditions.
