Carbonyl structure and polarity

Comparison of aldehyde and ketone structures with the carbonyl group, partial charges, and nucleophile attack site labelled

Aldehydes and ketones are both carbonyl compounds because they contain the C=O group. In an aldehyde the carbonyl group is at the end of the chain, while in a ketone it lies within the chain.

Step-by-step lessons on Eduqas A Level Chemistry Aldehydes and ketones. 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.
