• Molecular Framework: Aliphatic acyclic compounds
• Substituents: Ketone - Organic oxide - Hydrocarbon derivative - Aliphatic acyclic compound
• Description: This compound belongs to the class of organic compounds known as ketones. These are organic compounds in which a carbonyl group is bonded to two carbon atoms R2C=O (neither R may be a hydrogen atom). Ketones that have one or more alpha-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol.
• External Descriptors: Oxygenated hydrocarbons
