### Chemical Reaction Pathways of Alcohol under Different Conditions

This diagram illustrates the different chemical products that can be formed from the reaction of alcohol under varying conditions of temperature and in the presence of sulfuric acid (H₂SO₄).

#### Reaction Pathways

1. **Pathway a:**
   - **Reactant:** Alcohol
   - **Conditions:** in the presence of H₂SO₄, at 180°C
   - **Product:** 
     \[ \text{CH₃-CH=C-CH₃} \]
        |
       CH₃

2. **Pathway b:**
   - **Reactant:** Alcohol
   - **Conditions:** in the presence of H₂SO₄, at 180°C
   - **Product:** 
     \[ \text{CH₃-CH=CH₂} \]

3. **Pathway c:**
   - **Reactant:** Alcohol
   - **Conditions:** in the presence of H₂SO₄, at 140°C
   - **Product:** 
     \[ \text{CH₃-CH₂-O-CH₂-CH₃} \]

4. **Pathway d:**
   - **Reactant:** Alcohol
   - **Conditions:** in the presence of H₂SO₄, at 140°C
   - **Product:** 
     \[ \text{CH₃-CH-CH₂-O-CH₂-CH-CH₃} \]
        |                    |
      CH₃                CH₃

#### Explanation of Products Formed

- In **Pathways a and b**, the alcohol undergoes dehydration under high temperature (180°C) in the presence of H₂SO₄, resulting in the formation of alkenes.

- In **Pathways c and d**, the reaction occurs at a lower temperature (140°C) in the presence of H₂SO₄, leading to the formation of ethers.

These reaction pathways highlight the influence of reaction conditions, especially temperature, on the chemical products formed from alcohol.
