Elimination vs substitution

Elimination vs substitution

Elimination is the removal of a small molecule from an organic compound to make a double bond. In halogenoalkanes, hydroxide ion can help remove hydrogen and halogen from adjacent carbons, giving an alkene.

  3. /Elimination

Step-by-step lessons on AQA A Level Chemistry Elimination. Each one builds up to exam-style questions. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
