### Mechanism Proposal for Alkene Formation
**Question 3:**
Propose a mechanism for the formation of the 4 alkenes shown below from the reaction of 4-methylpentan-2-ol with aqueous sulfuric acid.
#### Reactant:
- **4-methylpentan-2-ol**: This is the starting alcohol structure with a hydroxyl (OH) group on the second carbon of a 4-methylpentane chain.
#### Reagents:
- **H₂SO₄** (sulfuric acid)
- **H₂O** (water)
#### Reaction Process:
- 4-methylpentan-2-ol undergoes dehydration in the presence of sulfuric acid and water, leading to the formation of alkenes.
#### Products:
Four different alkenes result from this dehydration reaction:
1. **Alkene 1**: Double bond between the second and third carbon atoms.
2. **Alkene 2**: Double bond between the first and second carbon atoms.
3. **Alkene 3**: Double bond between the third and fourth carbon atoms.
4. **Alkene 4**: Double bond between the fourth and fifth carbon atoms.
Each alkene has a structural representation showing a chain with varying positions of double bonds.
