In the reaction of an alkene with HBr, what is the major product formed?
Step 1: Identify the alkene you are working with. An alkene is a hydrocarbon that contains a carbon-carbon double bond.
Step 2: Understand that HBr is a hydrogen halide, which means it can add across the double bond of the alkene.
Step 3: Apply Markovnikov's rule, which states that when HBr adds to an alkene, the hydrogen (H) will attach to the carbon with the most hydrogen atoms already (the less substituted carbon).
Step 4: The bromine (Br) will then attach to the other carbon of the double bond, which is more substituted and therefore more stable.
Step 5: The result is the formation of an alkyl bromide, where the bromine is attached to the more substituted carbon, making it the major product.
