4-[(2-Fluoro-phen-yl)amino]-4-oxo-butanoic acid
Abstract:
The crystal structure of the title compound, C(10)H(10)FNO(3), contains dimers of the asymmetric unit, with R(2) (2)(8) rings arising from inter-molecular O-H⋯O hydrogen bonding through the carboxyl-ate groups. Adjacent dimeric units are connected to each other through one N-H⋯O and two C-H⋯O inter-molecular hydrogen bonds. C-H⋯O hydrogen bonds involving the aromatic ring and the O atoms of two carboxyl-ate groups form an R(3) (3)(7) ring. The crystal structure is further stabilized by C-H⋯F inter-actions, giving rise to a three-dimensional network.

IUPAC Nomenclature of Aldehydes
Organic Compounds
Nomenclature of Carboxylic Acid Derivatives: Acid Halides, Esters, and Acid Anhydrides
The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.
Carboxylic Acid Derivatives: Overview
IUPAC Nomenclature of Carboxylic Acids
For acyclic saturated monocarboxylic acids, the longest hydrocarbon chain containing the –COOH carbon is identified as the parent chain. Then, the last -e of the parent hydrocarbon name is replaced with a suffix -oic acid.
Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
