An amide is an organic compound that contains a carbonyl group (C=O) directly attached to a nitrogen atom from an amine. They are derived from carboxylic acids where the hydroxyl group is replaced by an amine or ammonia.
An organic compound and functional group containing a basic nitrogen atom with a lone pair, derived from ammonia by replacement of one or more hydrogen atoms by alkyl or aryl groups.
Carbonyl Group: A functional group composed of a carbon atom double-bonded to an oxygen atom (C=O), central to many organic chemical reactions
