### Educational Content: Stereochemistry Practice Problems#### 9. Identify the Indicated Groups in the Following Molecules as pro-R or pro-S:The problem features several molecular structures where specific groups are indicated with arrows. The task is to determine whether these groups are pro-R or pro-S, which involves assessing the potential chirality center configuration if the group were replaced by a higher priority substituent.1. **Molecule 1**: - Contains an amide group within a five-membered ring. The indicated group (arrow pointing to the hydrogen) is labeled as pro-R.2. **Molecule 2**: - A cyclic compound with an aldehyde (CHO) group. The hydrogen indicated by the arrow is not labeled, but assessment involves determining if a switch would lead to an R-configuration.3. **Molecule 3**: - A chain structure with a hydrogen indicated and two methyl groups adjacent. The task involves deciding pro-R or pro-S.4. **Molecule 4**: - A structure with a bromide group attached. One hydrogen is indicated; assign pro-R or pro-S.5. **Molecule 5**: - A cyclic ester-like structure. The indicated hydrogen is part of a chiral center under consideration for pro-R or pro-S labeling.6. **Molecule 6**: - Has a phenyl (Ph) group. The hydrogen indicated is one of the substituents, needing pro-R or pro-S assessment.7. **Molecule 7**: - Ethers with two oxygens in a three-membered ring. The configuration is assessed similarly.8. **Molecule 8**: - An acidic group is present (CO₂H). Assessment of indicated hydrogen involves determining if it will be pro-R or pro-S.#### 10. Identify the Indicated Faces in the Following Molecules as Re or Si:A series of molecular structures is presented, with specific faces indicated for stereochemical designation:- **Molecule 1**: - A molecule with labeling arrows pointing to faces needing evaluation depending on potential substituent arrival to result in re or si chirality.- **Molecule 2**: - Similar analysis is necessitated without specific molecular detail here.### Explanation of Terms:- **pro-R and pro-S**: Refer to the potential stereochemical outcome if replacing
