**Educational Resource on Stereochemistry** **1. Menthol Stereochemistry:** Menthol is a terpene with natural product origins, exhibiting two stereoisomeric forms: (1R,2S,5R) and (1S,2R,5S). You are tasked with drawing these two enantiomers in their most stable chair conformations and determining if they are enantiomers or diastereomers. A **chemical structure** of menthol is shown with an alcohol group (OH) attached to a cyclohexane ring. **2. Identifying Chiral Centers:** In the provided molecule, identify chiral centers and assign them as R or S configurations. The molecule contains several ring structures, an alcohol group, and an aldehyde group. **3. Chirality Analysis:** Analyze the chirality of the following molecules: - A five-membered ring with an attached group. - A linear molecule with bromine atoms attached. - A six-membered ring with chlorine atoms. - A polycyclic compound with hydrogen atoms, labeled with methyl groups (CH₃) and hydrogen. For these molecules, determine chirality, justify your reasoning and identify the chiral centers, assigning R or S configurations where applicable. This exercise enhances understanding of chiral centers, stereochemistry, and the differentiation between enantiomers and diastereomers.
