Below is a transcription and explanation of the chemical reactions occurring in the image related to 2-methyl-1-butene: The image outlines four different reactions involving 2-methyl-1-butene, as follows: 1. **Reaction A:** - **Reactants:** 2-methyl-1-butene and HBr in the presence of H₂O₂ - **Product:** A compound labeled as A, featuring a bromine (Br) atom on the second carbon, with the rest of the structure implied as unchanged. 2. **Reaction B:** - **Reactants:** 2-methyl-1-butene with water and H₃O⁺ - **Product:** A compound labeled as B, which contains an alcohol (OH) group on the tertiary carbon. 3. **Reaction D:** - **Reactants:** 2-methyl-1-butene with Br₂ and water (H₂O) - **Product:** A compound labeled as D, containing both a bromine (Br) and an alcohol (OH) group on adjacent carbons. 4. **Reaction C:** - **Reactants:** 2-methyl-1-butene undergoing hydroboration-oxidation: - Step 1: BH₃ - Step 2: H₂O₂ and NaOH - **Product:** A compound labeled as C, featuring an alcohol (OH) group on the less substituted carbon. These reactions represent different pathways for electrophilic addition and hydroboration oxidation in organic chemistry. Each reaction modifies the original alkene, 2-methyl-1-butene, into various functionalized derivatives.
