Which of the following chemical relationships properly classify compounds as Diastereomers? — Isomerism and Stereochemistry Chemistry Question

💡 Solution & Explanation

Diastereomers are any stereoisomers that do not share a mirror-image relationship. This broad definition encompasses geometrical isomers (cis/trans), optical diastereomers (like Erythrose and Threose), and the relationship between a chiral molecule and its corresponding meso form. D-Glucose and L-Glucose are perfect mirror images, rendering them Enantiomers.
