**Educational Content on Organometallic Nucleophile and Carbonyl Electrophile Combinations**

**Objective:**  
Provide all possible organometallic nucleophile and carbonyl electrophile combinations that lead directly to a given product after an acidic workup step.

**Instructions:**  
Please format your answers using a retrosynthetic arrow as demonstrated in the example.

---

**Example Reaction:**

- **Given Product:** A tertiary alcohol with a phenyl group and two methyl groups.
- **Retrosynthesis:**
  - Breaks down to a Grignard reagent (phenylmagnesium bromide) and acetone (carbonyl compound).

---

**Exercises:**

1. **Compound 1:**  
   - Structure: Cyclohexanone with an allylic alcohol group. 

2. **Compound 2:**  
   - Structure: Cyclohexanol derivative with a long alkyl chain.

3. **Compound 3:**  
   - Structure: Complex tertiary alcohol with three methyl groups and a propane chain.

**Notes on Retrosynthetic Analysis:**
- Identify the carbonyl precursor by locating potential functional groups that could have been derived from carbonyls.
- Determine the nucleophilic part of the organometallic reagent by considering the reduced part of the hydroxy group.
- Consider the stability of the organometallic reagent and the potential for reaction with carbonyl compounds.

**Conclusion:** This exercise will reinforce the students' understanding of retrosynthetic analysis and the application of organometallic reagents in forming alcohols.
