The term amide refers both to classes of compounds and to the functional group (R n E(O) x NR' 2) within those compounds.
The term amide refers both to classes of compounds and to the functional group (R n E(O) x NR' 2) within those compounds. Amide can also refer to the conjugate base of ammonia (the anion H 2 N −) or of an organic amine (an anion R 2 N −). For discussion of these  anionic amides, see Alkali metal amides. The remainder of this article is about the carbonyl-nitrogen sense of amide. In the usual nomenclature, one adds the term amide to the stem of the parent acid's name. For instance, the amide derived from acetic acid is named acetamide (CH 3 CONH 2). IUPAC recommends ethanamide, but this and related formal names are rarely encountered INTRODUCING AMIDES This page explains what amides are and looks at their simple physical properties such as solubility and melting points. What are amides? Amides are derived from carboxylic acids. A carboxylic acid contains the-COOH group, and in an amide the-OH part of that group is replaced by an-NH2 group. So. . . amides contain the-CONH2 group. Some simple amides The most commonly discussed amide is ethanamide, CH3CONH2 (old name: acetamide). Name each compound with the common name, the IUPAC name, or both. Solution. 1  This amide has two carbon atoms and is thus derived from acetic acid. 2  The OH of acetic acid is replaced by an NH 2 group. 3  The-ic from acetic (or-oic from ethanoic) is dropped, and-amide is added to give acetamide (or ethanamide in the IUPAC system). 4  This amide is derived from benzoic acid. 1 In chemistry, an amide is usually an organic compound that contains the functional group consisting of an acyl group (R-C=O) linked to a nitrogen atom (N).  An amide is a class of organic compounds containing a nitrogen atom attached to an acyl group. Amides are considered a derivative of carboxylic acids and can also be prepared from amines, anhydrides, esters, and nitriles. All peptide linkages in proteins are amides. A carboxylic acid and an amine react to form amide. Organic acids are characterized by an end carbon bonded to a carbonyl group (-C=O) and a hydroxyl group (-OH), collectively written as-COOH. The amines have organic groups bonded to a nitrogen atom. By Anne Marie Helmenstine, Ph.D. Definition: An amide is a functional group containing a carbonyl group linked to a nitrogen atom. Amide also refers to any compound containing the amide functional group. Amides are derived from carboxylic acid and an amine. Amide is also the name for the inorganic anion NH 2. It is the conjugate base of ammonia (NH 3) Medical Definition of AMIDE. : an organic compound derived from ammonia or an amine by replacement of an atom of hydrogen with an acyl group—compare imide. — amid·ic \ə-ˈmid-ik, a-\ adjective. Definition of AMIDE. 1. : an inorganic compound derived from ammonia by replacement of an atom of hydrogen with another element (as a metal). 2. : an organic compound derived from ammonia or an amine by replacement of an atom of hydrogen with an acyl group—compare imide. — amid·ic \ə-ˈmid-ik, a-\ adjective.
