What are the basic units in the structure of orthoboric acid? How are they linked?

Explanation

### Step-by-Step Solution:

1. **Identify the Chemical Formula**:
- Orthoboric acid is represented by the chemical formula H₃BO₃. However, it can also be expressed as BOH₃, which highlights the boron atom bonded to three hydroxyl (–OH) groups.

2. **Understand the Basic Units**:
- The basic units in the structure of orthoboric acid are the boron (B) atom and the hydroxyl (–OH) groups. Each boron atom is surrounded by three hydroxyl groups.
