Which of the following functional groups contains a carbonyl group bonded to a nitrogen atom?

Recall that an amide is a functional group where a carbonyl group is bonded to a nitrogen atom. The general structure of an amide is $RC=ONR\text{'}$, where R and R' are organic groups.

Compare the structures of the other functional groups: Alcohols contain an -OH group, Ethers have an -O- linkage between two carbon groups, and Aldehydes have a carbonyl group bonded to a hydrogen atom.
