Orthoamino

Orthoamino refers to a specific positional isomer in organic chemistry. In aromatic compounds, particularly benzene derivatives, substituents can be arranged in relation to each other at different positions on the ring. The prefixes "ortho," "meta," and "para" are used to denote these relative positions. When two substituents are on adjacent carbon atoms of a benzene ring, they are described as being in the ortho position to each other. Therefore, an "orthoamino" compound is an aromatic compound where an amino group (-NH2) is attached to a carbon atom that is adjacent to another substituted carbon atom on the aromatic ring.

For example, orthoaminophenol is a compound where an amino group and a hydroxyl group (-OH) are attached to adjacent carbon atoms on a benzene ring. Similarly, orthoaminobenzoic acid has an amino group and a carboxyl group (-COOH) in ortho positions. This specific arrangement of functional groups can significantly influence the chemical and physical properties of the molecule, including its reactivity, solubility, and potential for forming intramolecular hydrogen bonds. The ortho configuration is distinct from meta (one carbon atom between substituents) and para (two carbon atoms between substituents). Understanding the positional isomerism is crucial for predicting and explaining the behavior of organic molecules.
