Answer

To determine the non-planar species among the given ions: \(NO_3^-\), \(AsO_3^{3-}\), \(CO_3^{2-}\), \(ClO_3^-\), \(SO_3^{2-}\), and \(BO_3^{3-}\), we will analyze the hybridization and geometry of each species.

### Step-by-Step Solution:

1. **Identify Hybridization and Geometry**:
- **\(NO_3^-\)**:
- Nitrogen is bonded to three oxygen atoms with one double bond and two single bonds.
- Hybridization: \(sp^2\) (since it forms three sigma bonds and has no lone pairs).
- Geometry: Trigonal planar.

- **\(AsO_3^{3-}\)**:
- Arsenic is bonded to three oxygen atoms with one lone pair.
- Hybridization: \(sp^3\) (since it forms three sigma bonds and has one lone pair).
- Geometry: Pyramidal (non-planar).

- **\(CO_3^{2-}\)**:
- Carbon is bonded to three oxygen atoms with one double bond and two single bonds.
- Hybridization: \(sp^2\).
- Geometry: Trigonal planar.

- **\(ClO_3^-\)**:
- Chlorine is bonded to three oxygen atoms with one lone pair.
- Hybridization: \(sp^3\).
- Geometry: Pyramidal (non-planar).

- **\(SO_3^{2-}\)**:
- Sulfur is bonded to three oxygen atoms with one lone pair.
- Hybridization: \(sp^3\).
- Geometry: Pyramidal (non-planar).

- **\(BO_3^{3-}\)**:
- Boron is bonded to three oxygen atoms with no lone pairs.
- Hybridization: \(sp^2\).
- Geometry: Trigonal planar.

2. **Classify the Species**:
- **Planar Species**:
- \(NO_3^-\) (Trigonal planar)
- \(CO_3^{2-}\) (Trigonal planar)
- \(BO_3^{3-}\) (Trigonal planar)

- **Non-Planar Species**:
- \(AsO_3^{3-}\) (Pyramidal)
- \(ClO_3^-\) (Pyramidal)
- \(SO_3^{2-}\) (Pyramidal)

3. **Conclusion**:
- The non-planar species among the given ions are \(AsO_3^{3-}\), \(ClO_3^-\), and \(SO_3^{2-}\).

### Final Answer:
The non-planar species are \(AsO_3^{3-}\), \(ClO_3^-\), and \(SO_3^{2-}\).
