Questions & Step-by-Step Solutions

What is the product of the reaction between ethene and HBr?
  • Step 1: Start with ethene, which is a simple alkene with the formula C2H4.
  • Step 2: HBr is a hydrogen halide that can react with alkenes.
  • Step 3: The double bond in ethene is reactive and can break to allow new bonds to form.
  • Step 4: When HBr is added to ethene, the hydrogen (H) from HBr attaches to one carbon atom of the ethene.
  • Step 5: The bromine (Br) from HBr attaches to the other carbon atom of the ethene.
  • Step 6: This reaction results in the formation of bromoethane, which has the formula C2H5Br.
