Verified step by step guidance
1
Understand the structure of a carbonyl group. A carbonyl group consists of a carbon atom double-bonded to an oxygen atom, represented as .
Identify the functional groups listed in the problem: Amide, Alcohol, Ether, and Aldehyde.
Recall the structure of an amide. An amide contains a carbonyl group bonded to a nitrogen atom, represented as , where R represents a hydrocarbon chain.
Compare the structures of the other functional groups: Alcohols contain an -OH group, Ethers contain an -O- linkage between two carbon atoms, and Aldehydes contain a carbonyl group bonded to a hydrogen atom.
Conclude that among the given options, only the amide functional group contains a carbonyl group bonded directly to a nitrogen atom.
