Question

Hello can someone help me with the bottom problem i am confused and if anyone know a reagent list that would be helpful because online is all over the place. 

**Title:** Reagent Transformations in Organic Chemistry

**Description:** This guide details the reagents needed to accomplish specific organic transformations. Follow the steps and explanations precisely to ensure proper chemical reactions.

---

**Transformation 1**

**Reaction Scheme:**
1. Reagent: \( \text{CH}_3\text{CH}_2\text{MgBr} \)
2. Followed by: \( \text{H}_3\text{O}^+ \)

**Diagram Explanation:**
- The initial molecule is a ketone.
- Upon treatment with the Grignard reagent \( \text{CH}_3\text{CH}_2\text{MgBr} \) and subsequent protonation with \( \text{H}_3\text{O}^+ \), the ketone is converted into a secondary alcohol.
  
**Additional Step:**
3. Reagent: \( \text{HBr} \) or \( \text{TsCl} \)
   - This step involves the addition of a bromine or tosylation to the molecule.

**Notes:**
- Strong bases are more likely to deprotonate (remove the hydrogen) then kick off the bromine group, resulting in the formation of a different intermediate.

---

**Transformation 2**

**Reaction Scheme:**

1. Reagent: \( \text{KOh} \)

**Diagram Explanation:**
- The reaction starts with a bromoalkane.
- The addition of \( \text{KOh} \) introduces a base that can deprotonate and kick off the bromine atom, leading to the formation of an alkene.

**Notes (in orange):**
- Strong base: removes hydrogen, then kicks off bromine.

---

**Transformation 3**

**Reaction Scheme:**

1. Reagent: \( \text{H}_2 \) / \( \text{Pd} \)
2. Followed by: \( \text{H}_3\text{O}^+ \)
3. Reagent: \( \text{TsCl}, \text{py} \)
4. Reagent: \( \text{tBuok} \)

**Diagram Explanation:**
- This sequence involves an alkyne as the starting material.
- The first step uses hydrogen gas with palladium as a catalyst to reduce the alkyne to an alkene.
- Protonation with \( \text{H
