Question
**Question:**  
Pick out the process which does not involve carbocation formation:

1. **Reaction A:**  
   \[
   \text{Alkene (CH}_2\text{=CH}_2) \xrightarrow{\text{Br}_2/CCl_4} \text{Dibromoalkane (Br-CH}_2\text{-CH}_2\text{-Br)}
   \]

2. **Reaction B:**  
   \[
   \text{Tertiary alcohol} \xrightarrow{\text{HBr/ether}} \text{Tertiary bromoalkane}
   \]
   **Selected**

3. **Reaction C:**  
   \[
   \text{Tertiary alcohol} \xrightarrow{\text{H}_2\text{SO}_4/\text{H}_2\text{O}} \text{Alkene (CH}_3\text{-CH=CH}_2)
   \]

4. **Reaction D:**  
   \[
   \text{Alkene (CH}_2\text{=CH}_2) \xrightarrow{\text{HCl/ether}} \text{Chloroalkane (CH}_3\text{-CH}_2\text{-Cl)}
   \]

5. **Option E:**  
   - None of these involve a carbocation.

**Analysis:**
- **Reaction A and D** are examples of electrophilic addition to alkenes and typically do not involve the formation of carbocations.
- **Reaction B**, highlighted as the correct choice, involves an SN1 mechanism in which a carbocation is formed.
- **Reaction C** involves an E1 mechanism, also forming a carbocation. 

**Conclusion:**  
The highlighted choice indicates Reaction B does not involve carbocation formation, which appears incorrect unless additional context is provided.
