Question: What is the major product of the reaction of propene with HBr?

Options:

Correct Answer: 2-Bromopropane

Solution:

The major product of the reaction of propene with HBr is 2-bromopropane due to Markovnikov\'s rule.

What is the major product of the reaction of propene with HBr?

What is the major product of the reaction of propene with HBr?

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 already attached.
Step 4: Determine where H and Br will add. In propene, the first carbon has 2 H atoms and the second carbon has 1 H atom. According to Markovnikov's rule, H will attach to the first carbon.
Step 5: Attach Br to the second carbon. Since H goes to the first carbon, Br will go to the second carbon.
Step 6: Write the product. The product formed is 2-bromopropane (C3H7Br).
Step 7: Conclude that 2-bromopropane is the major product of the reaction.
