Question
**Instruction:** Draw the structure of any diastereomer of (2R,3S)-dichloropentane. Take particular care to indicate three-dimensional stereochemistry detail properly. **Explanation:** This instruction is asking for a chemical drawing of a diastereomer of the given compound. The key focus is on the correct depiction of stereochemistry, specifically the three-dimensional arrangements of the groups around the chiral centers. **Steps to Approach:** 1. **Understand the Compound:** - (2R,3S)-dichloropentane has two chiral centers at carbons 2 and 3. - The R and S configurations indicate the specific orientations of substituents around each chiral center according to Cahn-Ingold-Prelog priority rules. 2. **Determine Diastereomers:** - A diastereomer of (2R,3S)-dichloropentane will have one chiral center different from the given configuration. 3. **Drawing the Structure:** - Use wedge and dash notations to represent the three-dimensional geometry. - Indicate the chlorine atoms' positions on the chiral centers. - Ensure that the carbon chain is clear and bonds are properly oriented to show stereochemistry. This task requires an understanding of stereochemistry and the ability to represent molecular structures accurately in three dimensions.

Expert Solution
Step 1: Diastereomers

The isomers having same bond connectivity but differing in spatial orientation are called diastereomers. These isomers are not connected by non-superimposable mirror image relation, and are non-identical spatially.
