Explanation

To answer the question regarding an example of a compound in which hydrogen bonding results in the formation of a dimer, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Hydrogen Bonding**:
Hydrogen bonding occurs when a hydrogen atom covalently bonded to a highly electronegative atom (like oxygen, nitrogen, or fluorine) interacts with another electronegative atom. This interaction can lead to the formation of dimers in certain compounds.

2. **Identifying Compounds**:
