Stereoisomers in Nature?
In nature, molecules of the same chemical composition can have different physical properties. Explain, with suitable examples, how the presence of stereoisomers contributes to these variations. Discuss the significance of stereoisomerism in the study of natural products.

📌 CONCEPT: Stereoisomers are molecules with the same molecular formula and sequence of bonded atoms but differ in the three-dimensional arrangement of their atoms in space, resulting in different physical and chemical properties.
📐 RULE / FORMULA: The presence of stereoisomers can be predicted using the R-S configuration system, where the priority of groups attached to the chiral carbon atom is determined by a set of rules to assign an R or S configuration.
💡 WORKED EXAMPLE: Consider the molecule (2R,3S)-2-butanol and (2S,3R)-2-butanol, which are stereoisomers of each other. They have the same molecular formula (C4H10O) and sequence of bonded atoms but differ in the configuration at the chiral carbon atom, resulting in different physical and chemical properties.
⚠️ COMMON MISTAKE: Students often confuse stereoisomers with structural isomers and fail to recognize that stereoisomers have the same molecular formula, sequence of bonded atoms, but differ in the three-dimensional arrangement of their atoms in space.
