Q: What type of reaction occurs when an alkene reacts with HBr?
Solution: The reaction of an alkene with HBr is an addition reaction, where HBr adds across the double bond.
Steps: 6
Step 1: Identify the alkene, which is a molecule that has a carbon-carbon double bond.
Step 2: Recognize that HBr is a hydrogen bromide molecule, which can donate a hydrogen atom (H) and a bromine atom (Br).
Step 3: Understand that in an addition reaction, two reactants combine to form a single product.
Step 4: When HBr reacts with the alkene, the double bond between the carbon atoms breaks.
Step 5: The hydrogen atom from HBr attaches to one of the carbon atoms, and the bromine atom attaches to the other carbon atom.
Step 6: The result is a new molecule that has a single bond between the two carbon atoms, with one carbon bonded to a hydrogen and the other bonded to a bromine.
