Ester vs. Carbonyl: What's the Difference?

Any of a class of compounds derived from an oxyacid, usually resulting from the reaction of an oxyacid and an alcohol with the elimination of water.

The bivalent group C＝O.

(organic compound) A compound most often formed by the condensation of an alcohol and an acid, with elimination of water, which contains the functional group carbon-oxygen double bond (i.e., carbonyl) joined via carbon to another oxygen atom.

A metal compound, such as Ni(CO)4, containing the CO group.

An ethereal salt, or compound ether, consisting of an organic radical united with the residue of any oxygen acid, organic or inorganic; thus the natural fats are esters of glycerin and the fatty acids, oleic, etc.

(organic chemistry) In organic chemistry, a divalent functional group, (-CO-), characteristic of aldehydes, ketones, carboxylic acids, amides, carboxylic acid anhydrides, carbonyl halides, esters and others.

Formed by reaction between an acid and an alcohol with elimination of water

(inorganic chemistry) Any compound of a metal with carbon monoxide, such as nickel carbonyl, Ni(CO)₄.

The radical (CO)´´, occuring, always combined, in many compounds, as the aldehydes, the ketones, urea, carbonyl chloride, etc.

A compound containing metal combined with carbon monoxide

Relating to or containing the carbonyl group
