C. Symmetrical
D. None

Explanation

To determine the structure of hydrogen peroxide (H₂O₂) based on its dipole moment of 2.1 D, we can follow these steps:

### Step 1: Understand the Dipole Moment
The dipole moment is a measure of the separation of positive and negative charges in a molecule. A higher dipole moment indicates that the molecule has a significant difference in electronegativity between the bonded atoms and/or an asymmetrical shape.

**Hint:** Remember that a dipole moment indicates the presence of polar bonds and the overall shape of the molecule.

### Step 2: Draw the Structure of H₂O₂
Hydrogen peroxide has the following structure:
- Two oxygen atoms are bonded to each other.
- Each oxygen atom is also bonded to one hydrogen atom.

The Lewis structure can be represented as:
```
H H
\ /
O - O
```

**Hint:** Visualizing the molecular structure can help in understanding the spatial arrangement of atoms.

### Step 3: Analyze the Geometry
The molecular geometry of H₂O₂ can be analyzed by considering the bond angles and the arrangement of atoms:
- The bond angle between the O-O-H and O-H bonds is approximately 101.6 degrees, and the O-O bond has a bond angle of about 90.2 degrees.
- This indicates that the molecule does not have a linear shape.

**Hint:** Look for bond angles and the arrangement of atoms to determine if the structure is linear or non-linear.

### Step 4: Determine Symmetry
To assess whether the structure is symmetrical or not:
- The arrangement of the hydrogen and oxygen atoms is not symmetrical because the molecule has different atoms (H and O) and the bond angles are not equal.
- Therefore, H₂O₂ is considered to be an unsymmetrical molecule.

**Hint:** Symmetry can often be assessed by checking if the molecule can be divided into two identical halves.

### Step 5: Conclusion
Based on the analysis:
- The dipole moment of 2.1 D suggests that H₂O₂ is a polar molecule.
- The structure is non-linear due to the angles and arrangement of atoms.
- It is also unsymmetrical because of the different atoms and bond angles.

Thus, the correct answer is that the structure of H₂O₂ is non-linear.

**Final Answer:** The structure of H₂O₂ is non-linear (Option B).
