Question
Predicts the major parts of the following reaction. Making sure to pay attention to stereochemistry.
The image presents a chemical reaction scheme for the transformation of an alkene, specifically cyclohexene with a propyl group, using different reagents. The central molecule is the starting alkene. 1. **Hydrogenation Reaction**: - **Reagents**: H₂, Pd/C - **Direction**: Arrow pointing to the left. - **Description**: This reaction involves the addition of hydrogen (H₂) to the alkene in the presence of a palladium on carbon (Pd/C) catalyst, converting the alkene to an alkane by saturating the double bond. 2. **Hydroboration-Oxidation Reaction**: - **Reagents**: BH₃·THF followed by H₂O₂, NaOH - **Direction**: Arrow pointing to the right. - **Description**: This two-step reaction initially involves the addition of borane (BH₃) in tetrahydrofuran (THF) to the alkene. Subsequently, oxidation with hydrogen peroxide (H₂O₂) and hydroxide ion (NaOH) converts the organoborane intermediate to an alcohol. 3. **Hydrobromination Reaction**: - **Reagents**: HBr - **Direction**: Arrow pointing diagonally downward to the left. - **Description**: This reaction involves the addition of hydrobromic acid (HBr) to the alkene, resulting in the formation of a bromo-alkane via a Markovnikov addition mechanism. 4. **Bromination Reaction**: - **Reagents**: Br₂, CH₃OH - **Direction**: Arrow pointing diagonally downward to the right. - **Description**: This reaction involves the addition of bromine (Br₂) in methanol (CH₃OH) to the alkene, leading to vicinal dibromo formation with methanol as the solvent. These reactions are common transformations in organic chemistry, showcasing the reactivity of alkenes with various reagents to yield different functional groups.
