Questions & Step-by-Step Solutions

What is the primary product of the reaction between ethene and bromine?
Correct Answer: 1,2-dibromoethane
  • Step 1: Identify the reactants. The reactants are ethene (C2H4) and bromine (Br2).
  • Step 2: Understand the type of reaction. This is an electrophilic addition reaction.
  • Step 3: Recognize that ethene has a double bond between the two carbon atoms.
  • Step 4: The bromine molecule (Br2) approaches the double bond in ethene.
  • Step 5: One of the bromine atoms forms a bond with one of the carbon atoms in ethene, breaking the double bond.
  • Step 6: The other bromine atom forms a bond with the other carbon atom in ethene.
  • Step 7: The result is a new compound called 1,2-dibromoethane (C2H4Br2).
