### Question 3: Aldol Reaction of Acetone and 2-Pentanone

**Question:**
When a 1:1 mixture of acetone and 2-pentanone is treated with base, aldol products form. Draw a structural formula for all possible products.

**Explanation:**
An aldol reaction involves the formation of a β-hydroxy ketone (aldol) through a nucleophilic addition of a ketone enolate to another ketone. When a base is added to a mixture of acetone and 2-pentanone, enolates form and attack the carbonyl groups.

For the specific reaction between acetone and 2-pentanone, the reaction pathways and resulting products can be:

1. **Acetone Enolate Reacting with 2-Pentanone:**
   - Enolate from acetone attacks the carbonyl carbon of 2-pentanone.

2. **2-Pentanone Enolate Reacting with Acetone:**
   - Enolate from 2-pentanone attacks the carbonyl carbon of acetone.

3. **Self-Condensation Products:**
   - Both acetone and 2-pentanone can undergo self-condensation forming products where an acetone enolate reacts with another acetone molecule and a 2-pentanone enolate reacts with another 2-pentanone molecule.

This results in four main products:
- Acetone + 2-pentanone aldol product
- 2-pentanone + acetone aldol product
- Acetone self-aldol product
- 2-pentanone self-aldol product

Students are expected to draw the structural formulas for these products, showing the β-hydroxy ketone structures for each possible aldol product.
