COOH
strutural formula of the carboxyl group
----COOH
-COOH: it is a carbon double bonded to an oxygen, as well as a hydroxyl (OH) group, and another element.
The formula for an amino group is NH2, representing a nitrogen atom bonded to two hydrogen atoms. The formula for a carboxyl group is COOH, representing a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group (OH).
The molecule with only a carboxyl group is called formic acid, with the formula HCOOH. It consists of a carboxyl group, COOH, where the hydrogen atom is attached to the carbon and the hydroxyl group (-OH) is attached to the same carbon.
The carboxyl group is polar.
(NH2)-(RCH)-(COOH) = (amino group)-(central carbon + hydrogen + variable side group)-(carboxyl group)
I believe you are referring to the carboxyl group, which has the structural formula COOH. The carbon is double bonded to an oxygen atom and single bonded to a hydroxyl group. It can thus be thought of as a carbonyl group bonded to a hydroxyl group.
The chemical formula for the carboxyl ion is -COO−.
Functional groups like carboxylic acids and phenols can act as acids by donating a proton (H+) in a reaction. These functional groups contain an acidic hydrogen atom that can be released as a hydronium ion (H3O+).
The structural formula of 2-methylbutanoic acid after oxidation would involve adding a carboxyl group (-COOH) at the end of the molecule where the -OH group was located in the original alcohol. So the resulting molecule would be 2-methylbutanoic acid with a carboxyl group at the terminal carbon.
No. A carboxyl group is made up off carbon, oxygen, and hydrogen.
