Carbonyl vs. Acyl

The bivalent group C＝O.

An organic group having the general formula RCO-, derived from an organic acid.

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

(organic chemistry) Any of class of organic radicals, RCO-, formed by the removal of a hydroxyl group from a carboxylic acid.

(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.

An acid radical, as acetyl, malonyl, or benzoyl. An acyl radical can be depicted as R-CO-, where -CO- is the carbonyl group, and R is the group that characterizes the acyl moiety.

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

Any group or radical of the form RCO- where R is an organic group;

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
