Question
## Newman Projections for 2,3-Dibromobutane ### Overview: The image presents four Newman projections for 2,3-dibromobutane, a common study model in organic chemistry to understand stereochemistry. These projections illustrate different spatial arrangements of atoms when viewing along the bond between the second and third carbon atoms. ### Detailed Explanation of Projections: **Molecule A (R, R)**: - The front carbon (C2) has substituents: H, Br, and CH3. - The rear carbon (C3) has substituents: H, Br, and CH3. - Both chiral centers are in the R configuration. **Molecule B (S, S)**: - The front carbon (C2) has substituents: H, Br, and CH3. - The rear carbon (C3) has substituents: H, Br, and CH3. - Both chiral centers are in the S configuration. **Molecule C (R, S)**: - The front carbon (C2) has substituents: H, Br, and CH3. - The rear carbon (C3) has substituents: H, Br, and CH3. - The chiral center on the front carbon is in the R configuration. - The chiral center on the rear carbon is in the S configuration. **Molecule D (S, R)**: - The front carbon (C2) has substituents: H, Br, and CH3. - The rear carbon (C3) has substituents: H, Br, and CH3. - The chiral center on the front carbon is in the S configuration. - The chiral center on the rear carbon is in the R configuration. ### Questions: #### Select the relationship between molecules A and B: - Diastereomers - Enantiomers - Identical molecules #### Select the relationship between molecules C and D: - Diastereomers - Enantiomers - Identical molecules ### Explanation of Questions: - **Enantiomers** are a pair of molecules that are non-superimposable mirror images of each other, having opposite configurations at each chiral center. - **Diastereomers** are stereoisomers that are not mirror images of each other and hence have different configurations at one or more (but not all) chiral centers. - **Identical molecules** are molecules that
