What's the difference between amide and imide?

Amide


Definition:

  • (n.) A compound formed by the union of amidogen with an acid element or radical. It may also be regarded as ammonia in which one or more hydrogen atoms have been replaced by an acid atom or radical.

Imide


Definition:

  • (n.) A compound with, or derivative of, the imido group; specif., a compound of one or more acid radicals with the imido group, or with a monamine; hence, also, a derivative of ammonia, in which two atoms of hydrogen have been replaced by divalent basic or acid radicals; -- frequently used as a combining form; as, succinimide.
