**Question 18****Objective:** Determine the reagents necessary to carry out the following organic conversion.**Diagram:**- **Left Structure:** A straight chain alkene with a triple bond (alkyne) positioned along the chain. - **Right Structure:** A straight chain aldehyde with a carbon-oxygen double bond (carbonyl group) at the end of the chain.**Options:**1. **Option 1:** - Step 1: O₃ - Step 2: Zn/acetic acid2. **Option 2:** - Step 1: H₂O/H₂SO₄ - Step 2: PCC/CH₂Cl₂3. **Option 3:** - Step 1: 9-BBN - Step 2: H₂O₂/NaOH/H₂O - Step 3: CrO₃/H₂SO₄/H₂O4. **Option 4:** - Step 1: 9-BBN - Step 2: H₂O₂/NaOH/H₂O5. **Option 5:** - Step 1: PCC/CH₂Cl₂**Graph Explanation:** The reaction involves converting a carbon-carbon triple bond (alkyne) into a carbon-oxygen double bond (aldehyde). This type of reaction often involves oxidation and hydration steps, which are reflected in the potential reagent choices.
