The carbonyl group
The carbonyl group
Carbonyl compounds contain the functional group C=OC=OC=O. The two families you meet most often are aldehydes, RCHORCHORCHO, and ketones, RCOR′RCOR'RCOR′, where RRR and R′R'R′ are hydrocarbon groups.
Step-by-step lessons on Edexcel A Level Chemistry Carbonyl compounds. 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.
