Question

Draw the Zaitsev product formed when 2,3‑dimethylpentan‑3‑ol undergoes an E1 dehydration.

The image depicts a structural representation of a molecule undergoing an E1 (Elimination 1) reaction in the presence of phosphoric acid (H₃PO₄).

### Chemical Structure:
1. **Starting Material**: 
   - The molecule features a cyclohexane ring with two substituents:
     - A methyl group (CH₃) attached to one of the carbon atoms.
     - A hydroxyl group (OH) on the adjacent carbon.

2. **Reaction Conditions**:
   - The reaction is labeled as an E1 reaction, which stands for a unimolecular elimination reaction.
   - Phosphoric acid (H₃PO₄) is used as the acid catalyst.

### Reaction Explanation:
In an E1 reaction, the hydroxyl group (OH) is typically protonated and leaves, forming a carbocation intermediate. Subsequently, a hydrogen atom is removed from the adjacent carbon, resulting in the formation of a double bond, typically creating an alkene. This type of reaction involves two steps and first-order kinetics. 

The arrow indicates the direction of the reaction from the reactant to the product. The specifics of the product are not given in this diagram, but it will generally involve the formation of an alkene via dehydration.
