Quick explanation
Identify chiral carbon atoms in organic molecules
- This point belongs to Optical isomerism (A-level only), especially Optical isomerism (A-level only).
- You need to be able to identify chiral carbon atoms in organic molecules.
- The key ideas to know are atoms, carbon, and molecules.
- 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 molecules contains a chiral carbon atom?
Direct answer
B) CH3CH(OH)CH3 contains a chiral carbon atom.
Key terms
- Chirality: The 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
Misidentifying chiral centers: Always check the substituents attached to the carbon atom; if any two groups are the same, it is not chiral.
