Question
**Instructions:** Label each pair of molecules below as enantiomers, diastereomers, constitutional isomers, or identical. **Pair 1:** - Molecule A: - Structure: H₃C-C(OH)(H)-C(H)(OH)-CH₂OH - Molecule B: - Structure: H₃C-C(H)(OH)-C(OH)(H)-CH₂OH **Pair 2:** - Molecule A: - Structure: CO₂H-C(H)(H)-C(H₃)-CH₂ - Molecule B: - Structure: H-C(H)(HO-C(CH₃)₂)-OHC **Pair 3:** - Molecule A: - Structure: HO₂C-CH₂-C-CO₂H (five-membered ring) - Molecule B: - Structure: HO-CH(CH₂OH)-CO-CH₂ (five-membered ring with aldehyde group) **Pair 4:** - Molecule A: - Structure: HOCH₂-C(H)(OH)-C(OH)(H)-CHO - Molecule B: - Structure: OHC-C(H)(OH)-C(OH)(H)-CH₂OH **Pair 5:** - Molecule A: - Structure: Cl-CH-CH(CH₃)-H (Cl and CH₃ on chiral C) - Molecule B: - Structure: CH₃-C(H)(Cl)-CH₂-H **Pair 6:** - Molecule A: - Structure: Br-CH₂-CH₂-Br (four-membered ring) - Molecule B: - Structure: Br-CH₂-CH₂-Br (four-membered ring) **Pair 7:** - Molecule A: - Structure: Cl-CH-(CH₃)-CH(Cl)-H (two chiral centers) - Molecule B: - Structure: Cl-CH(CH₃)-C(H)(Cl)-H (two chiral centers) **Analysis:** Check the structures for chirality centers, mirror images, and connectivity. Determine if the pairs are enantiomers (non-superimposable mirror images), diastereomers (stereoisomers that are not mirror images), constitutional isomers (different connectivity), or identical (same structure and configuration).
