Carboxylate - Wikipedia
网页In organic chemistry, a carboxylate is the conjugate base of a carboxylic acid, RCOO− (or RCO− 2). It is an anion, an ion with negative charge. Carboxylate salts are salts that have the general formula M (RCOO)n, where M is a metal and n is 1, 2,....
Definition of Carboxyl Group in Chemistry - ThoughtCo
网页2020年1月14日 · In chemistry, the carboxyl group is an organic, functional group consisting of a carbon atom that's double-bonded to an oxygen atom and singly bonded to a hydroxyl group. Another way to view it is as a carbonyl group (C=O) that has a hydroxyl group (O-H) attached to the carbon atom.
20.2 Structure and Properties of Carboxylic Acids
网页2023年11月23日 · Carboxylic acids are organic compounds which incorporate a carboxyl functional group, CO 2 H. The name carboxyl comes from the fact that a carbonyl and a hydroxyl group are attached to the same carbon. The carbon and oxygen in the carbonyl are both sp2 hybridized which give a carbonyl group a basic trigonal shape.
What is the difference between carboxylate ions and groups?
网页When these salts are ionised (e.g. dissolved in water), the anion with the carboxylate group is called a carboxylate ion. The carboxylate ion is the negative ion (anion) formed as the conjugate base when a carboxylic acid loses a proton.
Carboxylate Group - Vocab, Definition, and Must Know Facts
网页The carboxylate group is a functional group consisting of a carbon atom double-bonded to an oxygen atom and singly-bonded to another oxygen atom, which carries a negative charge. This group is an important structural feature in many organic compounds and plays a key role in determining the acidity and reactivity of these molecules.
20.2 Structure and Properties of Carboxylic Acids - OpenStax
网页Structure and Properties of Carboxylic Acids. Highlights. Carboxylic acids are similar in some respects to both ketones and alcohols. Like ketones, the carboxyl carbon is sp2 -hybridized, and carboxylic acid groups are therefore planar with C–C═O and O═C–O bond angles of approximately 120° (Table 20.2).
20.2: Structure and Properties of Carboxylic Acids
网页Carboxylic acids are named such because they tend to be more acidic than other functional groups in organic chemistry. In dilute aqueous solutions, they act as Brønsted–Lowry acids and partially dissociate to produce the corresponding carboxylate ion and hydronium (H 3 O +).
21.1: Structure and Properties of Carboxylic Acids and their Salts
网页Carboxylic acids are organic compounds which incorporate a carboxyl functional group, CO 2 H. The name carboxyl comes from the fact that a carbonyl and a hydroxyl group are attached to the same carbon.
21.1 Naming Carboxylic Acid Derivatives - Organic Chemistry
网页Acid halides are named by identifying first the acyl group and then the halide. As described in Section 20.1 and shown in Table 20.1, the acyl group name is derived from the carboxylic acid name by replacing the -ic acid or -oic acid ending with -oyl, or the -carboxylic acid ending with -carbonyl.
1.9: Functional Groups - Biology LibreTexts
网页Carboxylic acid is a combination of a carbonyl group and a hydroxyl group attached to the same carbon, resulting in new characteristics. The carboxyl group can ionize, which means it can act as an acid and release the hydrogen atom from the …
