Questions & Step-by-Step Solutions

What is the product of the reaction between propene and HBr?
  • Step 1: Identify the reactants. We have propene (C3H6) and HBr (hydrobromic acid).
  • Step 2: Understand that HBr will add across the double bond in propene.
  • Step 3: Apply Markovnikov's rule, which states that the hydrogen (H) from HBr will attach to the carbon with more hydrogen atoms already attached.
  • Step 4: In propene, the double bond is between the first and second carbon. The first carbon has 3 hydrogens, and the second carbon has 1 hydrogen.
  • Step 5: According to Markovnikov's rule, the H from HBr will attach to the first carbon, and the Br will attach to the second carbon.
  • Step 6: This results in the formation of 2-bromopropane (C3H7Br) as the major product.
