Summary
This study reveals the planar structure of a C5H8O2 unsaturated carboxylic acid. Molecules form hydrogen-bonded dimers in the crystal structure, highlighting intermolecular interactions.
Area of Science:
- Crystallography
- Organic Chemistry
- Molecular Structure
Background:
- Understanding the molecular geometry and intermolecular forces of organic compounds is crucial.
- Carboxylic acids are fundamental functional groups in organic chemistry.
Purpose of the Study:
- To determine the crystal structure and molecular conformation of the title compound (C5H8O2).
- To investigate the intermolecular interactions present in the solid state.
Main Methods:
- Single-crystal X-ray diffraction was employed to analyze the crystal structure.
- Analysis of bond lengths, bond angles, and intermolecular contacts.
Main Results:
- The molecule of C5H8O2 was found to be essentially planar, with a maximum atomic displacement of 0.0239(13) Å.
- In the crystal lattice, molecules self-assemble into centrosymmetric dimers.
- These dimers are stabilized by a characteristic pair of O-H⋯O hydrogen bonds.
Conclusions:
- The title compound exhibits a planar molecular geometry in the solid state.
- Intermolecular hydrogen bonding plays a significant role in the crystal packing, leading to dimer formation.

Structure of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...

13.7K
IUPAC names of carboxylic acids are systematically derived following a few rules discussed below.
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.

Naming Acid Halides
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.

21.4K
Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

02:21Naming Enantiomers
28.0K
The naming of enantiomers employs the Cahn–Ingold–Prelog rules that involve assigning priorities to different substituent groups at a chiral center. Each enantiomer, being a distinct molecule, is assigned a unique name by the Cahn–Ingold–Prelog (CIP) rules, also called the R–S system. The prefix R- or S- attached to the chiral centers in an enantiomer is dependent on the spatial arrangement of the four substituents on the chiral center. The R–S system essentially comprises three...

Naming Amides
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.
