Definition
Isomers are molecules that have the same molecular formula but differ in the arrangement of their atoms; structural isomers vary in the connectivity of their atoms, cis-trans isomers (geometric isomers) differ in the spatial arrangement of groups around a double bond, and enantiomers are non-superimposable mirror images of each other.
Summary
Isomers are fascinating compounds that share the same molecular formula but differ in their atomic arrangements. This difference can lead to significant variations in their physical and chemical properties, making isomerism a crucial concept in chemistry. Understanding the types of isomers—structural, cis-trans, and enantiomers—helps students grasp the complexity of molecular interactions and behaviors. In practical applications, isomerism plays a vital role in fields like drug design, where the effectiveness of a medication can depend on its specific isomer. By studying isomers, learners can appreciate the importance of molecular structure in determining the properties and functions of compounds in real-world scenarios.
