The amino group (NH2) does not contain a carbon-oxygen double bond.
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.
CH3CH2CO2 contains an ester functional group. The carbon in the middle (C=O) is a carbonyl group, while the oxygen attached to the carbon on the right is part of an ester group.
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.
The functional group you are referring to is a carboxylic acid group, where the carbon atom is double bonded to an oxygen atom and also bonded to a hydroxyl group (-OH). It is commonly found in organic compounds like acetic acid.
Carbon dioxide has two double bonds between the carbon atom and each oxygen atom.
