![### Identification of Chiral Centers and Classification of Molecules
**Task:**
Examine the molecular structures provided to identify all chiral centers. Determine if each molecule is chiral or achiral. If the achiral molecules are meso, classify them accordingly.
**Molecular Structures:**
1. **Structure 1:** Contains a carbon bonded to an OH (hydroxyl) group and a Cl (chlorine) atom.
2. **Structure 2:** Contains a carbon with two OH (hydroxyl) groups.
3. **Structure 3:** Contains a carbon with no additional groups shown explicitly.
4. **Structure 4:** Cyclic structure with a three-carbon ring.
5. **Structure 5:** Contains a Cl (chlorine) attached to a chain with branching.
6. **Structure 6:** A cyclic structure featuring an OH (hydroxyl) group and a Br (bromine) atom.
7. **Structure 7:** A six-membered ring structure, with no explicit substituents shown.
**Instructions:**
- **Chiral Center Identification:** Look for carbon atoms bonded to four different groups.
- **Chirality Determination:** A molecule is chiral if it has at least one chiral center and lacks a plane of symmetry.
- **Meso Classification:** If a molecule is achiral and has chiral centers arranged in a way that creates a mirror plane, it may be classified as meso.
Consider these aspects while interpreting each molecule to complete the task.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fce0afc3b-3e57-4487-b673-cf6f07e8890b%2F14bd7e06-0fee-4bec-8707-76f3b4e95758%2Fa8yhqp_processed.jpeg&w=3840&q=75)
