Optical isomerism (A-level only)
Question
- A. When analyzing compounds with chiral centers.
- B. When comparing molecules with the same molecular formula but different connectivity.
- C. When studying the rotation of plane-polarised light.
- D. When identifying pairs of optical isomers.
Answer
When comparing molecules with the same molecular formula but different connectivity.
Explanation
Structural isomerism applies when molecules share the same molecular formula but differ in the connectivity of their atoms, leading to different structural arrangements. In contrast, optical isomerism is specifically concerned with chiral molecules that can rotate plane-polarised light. Thus, the application of structural isomerism is relevant in cases where the focus is on the arrangement of atoms rather than their optical properties.
Common mistake
Confusing Isomer Types
Students often confuse optical isomerism with structural isomerism, thinking they are the same.
Optical isomerism involves chiral molecules that rotate plane-polarised light, while structural isomerism involves different connectivity of atoms in a molecule. Focus on the definitions and characteristics of each type.
