### Conversion of Cyclohexanol to Various Compounds This diagram outlines the chemical reactions required to convert cyclohexanol into specific compounds. The process involves different conditions and reagents. Below are the possible conversion pathways: #### a. Conversion to Cyclohexene 1. **Option 1**: - **Reagents/Conditions**: \( \text{H}_2\text{SO}_4 \), heat - **Reaction**: Dehydration of cyclohexanol to form cyclohexene. 2. **Option 2**: - **Reagents/Conditions**: \( \text{H}_2\text{SO}_4 \), heat, followed by HBr - **Reaction**: Typically used for the formation of bromo-compounds, not directly related to cyclohexene formation. 3. **Option 3**: - **Reagents/Conditions**: \( \text{K}_2\text{Cr}_2\text{O}_7/\text{H}_2\text{SO}_4 \) - **Reaction**: An oxidation pathway, generally used for ketone formation, not suitable for cyclohexene. 4. **Option 4**: - **Reagents/Conditions**: \( \text{H}_2\text{SO}_4 \), heat, followed by \( \text{H}_2 \) with Pt catalyst - **Reaction**: Generally leads to hydrogenation, not directly to cyclohexene. #### b. Conversion to Cyclohexane 1. **Option 1**: - **Reagents/Conditions**: \( \text{H}_2\text{SO}_4 \), heat, followed by \( \text{H}_2 \) with Pt catalyst - **Reaction**: Hydrogenation of cyclohexene to form cyclohexane. 2. **Option 2**: - **Reagents/Conditions**: \( \text{H}_2\text{SO}_4 \), heat, followed by HBr - **Reaction**: Likely forms a bromo-compound, not cyclohexane. 3. **Option 3**: - **Reagents/Conditions**: \( \text{K}_2\text{Cr}_2\text{ ### Chemistry Reaction Pathways This image presents several chemical reaction pathways with different conditions and reagents.
