The molecular formula C2H4O may refer to: Acetaldehyde, Ethenol, Ethylene oxide From Wikipedia, the free encyclopedia Acetaldehyde, sometimes known as ethanal, is an organic chemical compound with the formula CH3CHO or MeCHO. It is a flammable liquid with a fruity smell. Acetaldehyde occurs naturally in ripe fruit, coffee, and fresh bread, and is produced by plants as part of their normal metabolism. It is popularly known as the chemical that causes hangovers. Ethenol, also called vinyl alcohol, hydroxyethene or hydroxyethylene, is an alcohol with chemical formula C2H3OH (H2C=CHOH) and CAS number 557-75-5. Under normal conditions, it tautomerizes to acetaldehyde. For this reason the thermoplastic polyvinyl alcohol (PVA or PVOH), which would be derived from this monomer, is made indirectly by polymerization of vinyl acetate followed by hydrolysis of the ester bonds. The chemical compound ethylene oxide is an important industrial chemical used as an intermediate in the production of ethylene glycol and other chemicals, and as a sterilant for foods and medical supplies. It is a colorless flammable gas or refrigerated liquid with a faintly sweet odor. It is the simplest example of an epoxide. Caffeine is a bitter white crystalline xanthine alkaloid that acts as a psychoactive stimulant drug and a mild diuretic (speeds up urine production ...
