Predict the relative ease of dehydration of the following alcohols

**Predict the Relative Ease of Dehydration of the Following Alcohols**

This image presents structural diagrams of three alcohols, asking for predictions on their relative ease of dehydration.

1. **First Alcohol (Left)**
   - Structure: \( \text{H}_3\text{C}-\text{CH}_2-\text{OH} \)
   - This represents a primary alcohol, specifically ethanol.

2. **Second Alcohol (Middle)**
   - Structure: 
     ```
     OH
      |
     CH
    /  \
   CH3  CH3
     ```
   - This represents a secondary alcohol, specifically isopropanol (2-propanol).

3. **Third Alcohol (Right)**
   - Structure: 
     ```
        CH3
         |
     H3C-C-CH3
         |
        OH
     ```
   - This represents a tertiary alcohol, specifically tert-butanol (2-methyl-2-propanol).

**Explanation for Dehydration Ease**:
- Tertiary alcohols usually dehydrate more easily than secondary and primary alcohols due to carbocation stability. Dehydration follows the order: tertiary > secondary > primary, based on the stability of the carbocation formed during the reaction. Therefore, tert-butanol should dehydrate most easily, followed by isopropanol, and then ethanol.
