**Transcription for Educational Website**---**Instructions:**Draw the **major product(s)** of the following reactions, if there is a reaction. **Be sure to include stereochemistry in your products.**---**Reactions:**1. Cyclopentanecarbonitrile (a five-membered ring with a cyanide group) reacting with $ \text{H}_3\text{O}^+ $. 2. Methyl ketone with a benzene ring on one side reacts with $ 3 \, \text{I}_2 $ / $ \text{NaOH} $. 3. Propanal (a three-carbon aldehyde) with ethylene glycol in the presence of $ \text{H}_3\text{O}^+ $.4. Cyclohexanone reacts in two steps: - Step 1: $ \text{LDA} $, $ \text{THF} $ - Step 2: 2-methylpropanal (a four-carbon aldehyde with a methyl group on the second carbon).---**Explanation of Diagrams and Reactions:**- **Diagram 1:** The structure shows a cyclopentane ring with a nitrile group ($-C \equiv N$). When hydrolyzed with $ \text{H}_3\text{O}^+ $, it will likely result in a carboxylic acid.- **Diagram 2:** The compound is a phenyl methyl ketone. The reaction conditions suggest iodination under basic conditions, likely leading to the formation of iodoform and a carboxylate ion.- **Diagram 3:** Shows aldehyde protection as an acetal. Propanal reacts with ethylene glycol in acidic conditions leading to the formation of a cyclic acetal.- **Diagram 4:** This is an enolate formation followed by an aldol reaction. Cyclohexanone forms its enolate with LDA, then reacts with 2-methylpropanal to form a β-hydroxy ketone. **Note:** For all reactions, consider any possible stereochemical outcomes and depict them in your structural representations.

Question

**Transcription for Educational Website**

**Instructions:**

Draw the **major product(s)** of the following reactions, if there is a reaction. **Be sure to include stereochemistry in your products.**

---

**Reactions:**

1. Cyclopentanecarbonitrile (a five-membered ring with a cyanide group) reacting with $ \text{H}_3\text{O}^+ $.

2. Methyl ketone with a benzene ring on one side reacts with $ 3 \, \text{I}_2 $ / $ \text{NaOH} $.

3. Propanal (a three-carbon aldehyde) with ethylene glycol in the presence of $ \text{H}_3\text{O}^+ $.

4. Cyclohexanone reacts in two steps:
- Step 1: $ \text{LDA} $, $ \text{THF} $
- Step 2: 2-methylpropanal (a four-carbon aldehyde with a methyl group on the second carbon).

---

**Explanation of Diagrams and Reactions:**

- **Diagram 1:** The structure shows a cyclopentane ring with a nitrile group ($-C \equiv N$). When hydrolyzed with $ \text{H}_3\text{O}^+ $, it will likely result in a carboxylic acid.

- **Diagram 2:** The compound is a phenyl methyl ketone. The reaction conditions suggest iodination under basic conditions, likely leading to the formation of iodoform and a carboxylate ion.

- **Diagram 3:** Shows aldehyde protection as an acetal. Propanal reacts with ethylene glycol in acidic conditions leading to the formation of a cyclic acetal.

- **Diagram 4:** This is an enolate formation followed by an aldol reaction. Cyclohexanone forms its enolate with LDA, then reacts with 2-methylpropanal to form a β-hydroxy ketone.

**Note:** For all reactions, consider any possible stereochemical outcomes and depict them in your structural representations.
