Questions & Step-by-Step Solutions

Which reaction mechanism is primarily involved in the addition of HBr to an alkene?
  • Step 1: Identify the alkene, which is a molecule with a carbon-carbon double bond.
  • Step 2: Recognize that HBr is a strong acid that can donate a proton (H+).
  • Step 3: Understand that the double bond in the alkene acts as a nucleophile, meaning it can donate electrons.
  • Step 4: The H+ from HBr attacks one of the carbon atoms in the double bond, forming a carbocation (a positively charged carbon).
  • Step 5: The Br- ion (the bromide ion) then attacks the carbocation, resulting in the addition of Br to the alkene.
  • Step 6: The final product is an alkyl bromide, where H and Br are added across the double bond.
