### Reaction Scheme
**c)**
- **Starting Compound:** Cyclohexene
- **Reagent:** Br₂, H₂O
- **Product:** The product box is blank, indicating an expected outcome of a bromohydrin formation, where bromine (Br) and a hydroxyl group (OH) are added across the double bond of cyclohexene.
**d)**
- **Starting Compound:** 1,1,1-Trifluoro-3-methylbut-2-ene
- **Reagent:** HI (Hydrogen Iodide)
- **Product:** The product box is blank, indicating an expected outcome of an addition reaction where iodine is added across the double bond, and possibly the fluorine atoms remain unaffected.
**e)**
- **Starting Compound:** Norbornane with a hydrogen at a bridgehead
- **Reagent:** Not specified (blank reagent box)
- **Product:** A norbornenol structure, indicating an alcohol (OH) group addition, suggesting that the unspecified reagent could be an oxidizing agent or involves an hydroxylation reaction.
**f)**
- **Reagent:** Br₂
- **Product:** The product is a dibromo compound with two phenyl rings, indicating that the starting compound (blank in the image) was likely a diphenylethylene structure. The product shows bromine atoms added on the carbon chain between the two benzene rings.
### Explanation:

Transcribed Image Text:### Organic Reaction Pathways
#### Reaction Pathway A
**Reactant:**
- A molecule with a cyclohexene ring, containing one double bond.
- It has two methyl groups (Me) and a hydroxyl group (OH).
- An additional carbonyl group (C=O) is present.
**Reagents:**
- Iodine (I₂)
- Potassium iodide (KI)
- Sodium bicarbonate (NaHCO₃)
**Product:**
- A compound with the molecular formula C₉H₁₃O₂I.
**Reaction Description:**
- This is a halogenation reaction involving iodine. The presence of sodium bicarbonate suggests a basic environment, which may aid in the reaction's progress.
#### Reaction Pathway B
**Reagents:**
- Borane (BH₃)
- Followed by hydrogen peroxide (H₂O₂) and sodium hydroxide (NaOH).
**Product:**
- A molecule with a cyclopentane ring, featuring one alcohol group (OH) and two methyl groups (Me) on adjacent carbon atoms.
**Reaction Description:**
- This process is likely a hydroboration-oxidation, which typically converts alkenes into alcohols, with borane acting first to add BH₂ and then the alcohol formation via oxidation with hydrogen peroxide in the presence of sodium hydroxide.
### General Concepts
- **Halogenation Reactions:** These involve the addition of halogens like iodine to unsaturated bonds, usually facilitated by catalysts or solvents.
- **Hydroboration-Oxidation:** A two-step process that adds a hydroxyl group across an alkene, converting it into an alcohol. The borane acts as a reducing agent, and subsequent oxidation yields the alcohol.
Understanding these reactions is crucial in synthetic organic chemistry for creating varying functional groups and structural motifs in complex molecules.
