Definitions:

Tertiary Amides

Amides derived from carboxylic acids where the nitrogen atom is bonded to three other carbon atoms, not including the carbonyl carbon.

Secondary Amides

Organic compounds characterized by a carbonyl group (C=O) attached to a nitrogen atom, which in turn is bonded to two alkyl or aryl groups.

Acid Chlorides

Reactive derivatives of carboxylic acids where the hydroxyl group is replaced with a chlorine atom, used in organic synthesis.

Nitriles

Organic compounds containing the cyano group (-C≡N), which consists of a carbon atom triple-bonded to a nitrogen atom.
