Quick explanation
Distinguish optical isomerism from structural isomerism
- This point belongs to Optical isomerism (A-level only), especially Optical isomerism (A-level only).
- You need to be able to distinguish optical isomerism from structural isomerism.
- The key ideas to know are optical isomer.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Optical isomerism (A-level only) to exam-style questions, flashcards, and revision notes for Optical isomerism (A-level only).
Quick student answer
Which of the following statements correctly distinguishes optical isomerism from structural isomerism?
Direct answer
Optical isomers have the same structural formula but differ in the arrangement of atoms in space.
Key terms
- Chirality: A property of a molecule that makes it non-superimposable on its mirror image.
- Enantiomer: One of two stereoisomers that are mirror images of each other.
Common trap
Confusing optical isomerism with structural isomerism: Remember that optical isomerism involves non-superimposable mirror images, while structural isomerism involves different connectivity of atoms.
