What is the key difference between an amine and an amide in terms of their chemical structures and properties?

The key difference between an amine and an amide is in their chemical structure. Amines have a nitrogen atom bonded to one or more carbon atoms, while amides have a nitrogen atom bonded to a carbonyl group (CO). This structural difference leads to differences in their properties, with amines typically being more basic and amides being more stable and less basic.
