In the study of organic chemistry, distinguishing between molecules that share the same molecular formula is crucial. This article explores enantiomers vs diastereomers vs constitutional isomers vs identical, providing clear definitions, examples, and the key features that set each category apart.
It's the bit that actually matters in practice.
What Are Isomers?
Isomers are compounds that possess the same molecular formula but differ in the arrangement of atoms. The term isomer encompasses several sub‑categories, each reflecting a different type of structural or spatial variation.
Among the most frequently encountered categories are constitutional isomers, also known as structural isomers, which arise when atoms are connected in different orders. To give you an idea, the molecular formula C₄H₁₀ can describe either
