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.

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.
