C11H15N

C11H15N is a molecular formula used to describe a family of organic compounds that contain eleven carbon atoms, fifteen hydrogen atoms, and one nitrogen atom. It does not designate a single substance, but rather many structural isomers share this formula.

Chemistry: The formula has a degree of unsaturation of five (calculated as 2C + 2 + N − H all divided by 2). This indicates that the molecules may include rings and/or multiple bonds, such as aromatic rings, double bonds, or heterocyclic structures. The presence of one nitrogen atom suggests possible nitrogen-containing functional groups, most commonly amines, but other N-containing moieties are also possible.

Typical classes: The formula can correspond to various nitrogen-containing compounds, including primary, secondary, or tertiary amines, anilines, and heterocycles. Without a defined structure, it is not possible to assign a single set of chemical or physical properties.

Properties and uses: Physical properties such as melting and boiling points, solubility, and odor depend on the exact arrangement of atoms. The approximate molecular weight is about 161.25 g/mol. Compounds with this formula may be used as intermediates in organic synthesis, research chemicals, or in pharmaceuticals, depending on the intended structure.

Notes: In chemical databases, C11H15N serves as a generic entry for molecules with that formula. When a specific compound is required, its full structural formula and IUPAC name are used.
