Explanation

To determine which ether is present in clove oil, we will analyze the options provided and identify the correct compound.

### Step-by-Step Solution:

1. **Understanding Ethers**: Ethers are organic compounds that contain an ether group, which consists of an oxygen atom bonded to two alkyl groups. The alkyl groups can be the same or different.

2. **Analyzing the Options**:
- **Option 1: Anethol**: Anethol is known to be present in the essential oil of Guarana and has psychoactive effects. It is not found in clove oil. Therefore, this option is incorrect.

- **Option 2: Usinol**: The IUPAC name for usinol is 4-allyl-2-methoxyphenol. This compound is naturally found in several food items, including clove buds, cinnamon, and other herbs. Since usinol is present in clove oil, this option is correct.

- **Option 3: Vanillin**: Vanillin is primarily used as a flavoring agent and is known for its presence in vanilla. It is not specifically associated with clove oil, making this option incorrect.

- **Option 4: Thymol**: Thymol is a phenol derivative found in thyme oil and is extracted from Thymus vulgaris. It is not present in clove oil, so this option is also incorrect.

3. **Conclusion**: Based on the analysis, the ether that is present in clove oil is **Usinol**.

### Final Answer:
The ether present in clove oil is **Usinol**.
