Question

Which of the following are meso compounds

**Choose one or more:**

1. **Epimer at a chiral carbon in a brominated cyclopentane:**
   - Structure: Cyclopentane ring with two bromine (Br) atoms and two hydrogen (H) atoms on the chiral centers. The methyl groups (CH₃) are positioned on opposite sides.
   - Highlights: This stereochemical configuration allows different spatial arrangements due to chiral carbons, essential in stereochemistry.

2. **Bicyclic brominated structure with chirality:**
   - Structure: Bicyclic framework featuring two six-membered rings. Prominent stereochemistry with bromine, hydrogen, and methyl groups.
   - Highlights: The placement of groups indicates a stereochemical relationship crucial for understanding chiral interactions.

3. **Trans-dibromocyclobutane:**
   - Structure: Four-membered cyclobutane with two bromine atoms across from each other in a trans orientation and two hydrogen atoms.
   - Highlights: Trans arrangement influences the molecule's properties, important in discussions about geometric isomerism.

4. **Oxirane with substituents:**
   - Structure: A three-membered epoxide ring (oxirane) with hydrogen and methyl groups creating asymmetric centers.
   - Highlights: The ring strain and substituent positioning are vital for reactions involving epoxides, impacting both reactivity and synthesis.

Each structure demonstrates unique aspects of stereochemistry and reactivity significant in organic chemistry studies.
