Question

draw the organic product for each

### Chemical Reactions and Synthesis Pathways

This image presents several organic chemistry reactions where the task is to draw the organic product for each transformation. The reactions are depicted with the starting material on the left, followed by the reaction conditions or reagents, and an arrow indicating the transformation.

1. **Reaction 1:**
   - **Starting Material:** A diketone compound.
   - **Reagent/Conditions:** \( \text{H}_3\text{PO}_4 \) (conc.)
   - **Task:** Identify the organic product resulting from an intramolecular reaction facilitated by phosphoric acid, likely involving cyclization or dehydration.

2. **Reaction 2:**
   - **Starting Material:** A phenolic ketone.
   - **Reagents/Conditions:**
     - Step 1: \( \text{NaBH}_4, \text{CH}_3\text{OH} \)
     - Step 2: \( \text{HCl, H}_2\text{O} \)
   - **Task:** Determine the product of the reduction of the ketone to an alcohol followed by work-up with hydrochloric acid and water.

3. **Reaction 3:**
   - **Starting Material:** A linear secondary alcohol.
   - **Reagents/Conditions:** Reaction with an epoxide in the presence of pyridine.
   - **Task:** Predict the nucleophilic substitution product where the alcohol acts as a nucleophile opening the epoxide ring.

4. **Reaction 4:**
   - **Starting Material:** A bromobenzene compound.
   - **Reagents/Conditions:**
     - Step 1: \( \text{Mg}, \text{CH}_3\text{CH}_2\text{OCH}_2\text{CH}_3 \) (formation of Grignard reagent)
     - Step 2: \( \text{CO}_2 \)
     - Step 3: \( \text{HCl, H}_2\text{O} \)
   - **Task:** Form a carboxylic acid by carbonation of the Grignard reagent and subsequent acid work-up.

5. **Reaction 5:**
   - **Starting Material:** A diketone linked by a flexible alkyl chain.
   - **Reagents/Conditions:**
     - Step 1: Reaction with phenylmagnesium bromide (PhMgBr)
