There are many. One with only oxygen and carbon would be carbonyl with a carbon double bonded to an oxygen.
The amino group (NH2) does not contain a carbon-oxygen double bond.
At the end of the molecule C is equal to O it is an aldehyde. Carbon has 3 bonds to form and an alcohol would have COH2. The last section is CO and the Carbon and Oxygen are double bonded.
An ene-one molecule must have both an alkene (ene) and a ketone (one) functional group. The alkene functional group is characterized by a carbon-carbon double bond, while the ketone functional group consists of a carbon double-bonded to an oxygen and attached to two other carbon groups.
Carbonyl
An aldehyde contains a carbonyl group, which is a carbon atom double-bonded to an oxygen atom.

A carbonyl group (C=O) is the functional group found in a ketone. It consists of a carbon atom double-bonded to an oxygen atom.
The functional group in methylenedioxypyrovalerone is a ketone group, which is a carbonyl group located within a carbon chain. The ketone group is characterized by a carbon double-bonded to an oxygen atom, with the carbon also bonded to two other carbon atoms.
>C=O group or keto group
Carbonyl
A group of carbon and oxygen bonded together is called a carbonyl group. This functional group consists of a carbon atom double-bonded to an oxygen atom. It is commonly found in organic compounds such as aldehydes, ketones, carboxylic acids, and esters.
When the carbonyl group is eliminated from a molecule, the functional group that is removed is the carbonyl group itself, which consists of a carbon atom double-bonded to an oxygen atom.
There are two oxygen double bonded to one carbon. DOUBLE BOND.
