Q: What is the major product of the reaction between propene and HBr?
Solution: The major product is 2-bromopropane due to Markovnikov's rule, where H adds to the less substituted carbon.
Steps: 7
Step 1: Identify the reactants. We have propene (C3H6) and HBr (hydrobromic acid).
Step 2: Understand the structure of propene. Propene has a double bond between the first and second carbon atoms.
Step 3: Apply Markovnikov's rule. This rule states that when HX (like HBr) adds to an alkene, the hydrogen (H) will attach to the carbon with more hydrogen atoms (the less substituted carbon).
Step 4: Determine the carbon atoms in propene. The first carbon (C1) has 3 hydrogen atoms, and the second carbon (C2) has 1 hydrogen atom.
Step 5: Add H from HBr to the less substituted carbon (C1). This means H will attach to C1.
Step 6: The Br from HBr will then attach to the more substituted carbon (C2).
Step 7: Write the product. The product formed is 2-bromopropane, where Br is attached to C2 and H is attached to C1.
