The TLC results indicate that the reactant has diminished and two new products have formed. The task is to analyze the candidate structures to identify which could be the products of this reaction. The reaction likely involves electrophilic addition of HBr to the alkene, leading to the formation of bromoalkanes. The goal is to match the observed products with the correct structures from the provided options."}
