Amide - Wikipedia
In organic chemistry, an amide, [1] [2] [3] also known as an organic amide or a carboxamide, is a compound with the general formula R−C(=O)−NR′R″, where R, R', and R″ represent any group, typically organyl groups or hydrogen atoms.

Organic Nitrogen Compounds, VII: Amides—The Rest of the Story
2020年1月1日 · Amides come in primary, secondary, and tertiary forms. The diagnostic pattern of peaks for primary amides is a pair of N-H stretching peaks and a C=O stretch. The pattern for secondary amides is one N-H stretch, a C=O stretch, and an intense N-H in-plane bend next to the C=O stretch.
21.7: Chemistry of Amides - Chemistry LibreTexts
The carbonyl bond is reformed along with the elimination of an amide ion (-NHR) leaving group (note this is a different use of the word amide meaning an amine anion), forming a carboxylic acid. In the last step, the amide ion deprotonates the carboxylic acid to form a carboxylate salt and an amine as products.

2023年1月23日 · Amides are derived from carboxylic acids. A carboxylic acid contains the \ (-COOH\) functional group, and in an amide the \ (-OH\) part of that group is replaced by an \ (-NH_2\) group. So, amides contain the \ (-CONH_2\) group.

2019年10月7日 · Amides are carboxylic acid derivatives where the –OH of the carboxylic acid has been replaced by –NH 2, –NHR, or –NR 2 of an amine. Since the reaction between a carboxylic acid and an amine to give an amide also liberates water, this is …
Amide: Definition, Structure, Nomenclature, and Examples
An amide is a fundamental class of organic compounds characterized by their distinct chemical structure, consisting of a carbonyl group (C=O) bonded to a nitrogen atom (N). This carbonyl-nitrogen linkage is a defining feature of amides and imparts unique properties and reactivity to these compounds [1-4].
Amide Definition and Examples in Chemistry - ThoughtCo
2019年12月4日 · An amide is a functional group containing a carbonyl group linked to a nitrogen atom or 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).
21.7 Chemistry of Amides - Organic Chemistry - OpenStax
Basic hydrolysis occurs by nucleophilic addition of OH – to the amide carbonyl group, followed by elimination of amide ion (– NH 2) and subsequent deprotonation of the initially formed carboxylic acid by ammonia. The steps are reversible, with the equilibrium shifted toward product by the final deprotonation of the carboxylic acid.
