ester
The group you are looking for is the "carboxyl" group -COOH. It should be noted, however, that while the carboxyls are by far the most common organic acids, there are other groups that can impart acidity to organic compounds as well, such as the sulphonics, SO2OH.
Aldehyde and ketones .
An amino acid always has an amino group and a carboxyl group. The amine group of one amino acid is capable of forming a peptide bond with the carboxyl group of another amino acid.
A carboxyl group (-COOH) functions as an organic acid (deprotonate to -COO-). An amino group (-NH2) may function as an organic base (protonated to -NH3+). Therefore an organic compound that has a carboxyl group is likely to have an acidic pH and an organic compound with an amino group is likely to have a basic pH (precise degree of acidity and basicity depends on the number of carbons in th backbone, the number of carboxyl or amino groups, and the presence of other functional groups).Some molecules that have both carboxyl groups and amino groups (amino acids, for example) can function as either an acid or a base under different circumstances, making them useful in buffering the pH of solutions.
ester
No. Organic acids contain carbon and a carboxyl group. Sulphuric acid contains hydrogen, sulphur, and oxygen.
No. But hydrogen bond can be formed between two carboxyl groups.
No. Organic acids contain carbon and a carboxyl group. Sulphuric acid contains hydrogen, sulphur, and oxygen.
a carboxyl group, -COOH
No. A carboxyl group is made up off carbon, oxygen, and hydrogen.
The group you are looking for is the "carboxyl" group -COOH. It should be noted, however, that while the carboxyls are by far the most common organic acids, there are other groups that can impart acidity to organic compounds as well, such as the sulphonics, SO2OH.
Organic acids
-COOH is the carboxyl functional group, which is called carboxylic acids, or organic acids. This is what gives vinegar its sour taste. It has acidic properties because of the hydrogen ion and found in ionic forms in cells, which is called carboxylate group.
n.An atom or group of atoms, such as a carboxyl group, that replaces hydrogen in an organic compound and that defines the structure of a family of compounds and determines the properties of the family.Read more: functional-group
