The functional group of the ketones is -CO-. The carbon atom is double bonded to the oxygen. The groups connected to the remaining bonds are alkyl or aryl groups (not hydrogen, which would result in the formation of an aldehyde). The alkyl or aryl...

Ketones have the general formula RCCOCR' where R and R' may be the same or different groups (they can be alkyl or aryl groups but not hydrogen). The central carbon atom has a double bond with the oxygen. Ketones differ from aldehydes in that the latter...

Ketones belong to a class of organic compounds known as carbonyls. They contain a carbon atom linked to an oxygen atom with a double bond (C=O). Acetone (dimethyl ketone) is a ketone commonly used in industrial applications. Other ketones include...

A type of organic compound having a carbonyl functional group (C=O) attached to two alkyl groups. Acetone is the simplest example of a...

A ketone (pronounced as key tone) is either the functional group characterized by a carbonyl group (O=C) linked to two other carbon atoms or a chemical compound that contains this functional group. A ketone can be generally represented by the...

Federal officials said early inspections indicate the crew of a CSX train acted properly just before it derailed, igniting a massive chemical fire that forced evacuations south of Louisville.The fire sent thick black clouds of smoke into the sky, prompting officials to evacuate residents and...

Drinking a milkshake-style medicine at breakfast seems to feed brain cells starved from Alzheimer's damage, researchers reported Monday. It's one of four promising experimental drugs poised for large-scale testing against the brain-destroying disease.The milkshake drug, called Ketasyn, is a dramatically different way to approach dementia....

Several train cars carrying volatile chemicals derailed and exploded Tuesday south of Louisville, shutting down a highway and forcing evacuations of homes, businesses and a school, authorities said.No serious injuries were reported, but at least 11 people near the crash checked themselves into a hospital...
