Published on: April 19, 2019
Summary
Carbyne, a new form of elemental carbon, is being reevaluated for its existence and role in meteorites. Further research is needed to confirm its presence and properties.
Area of Science:
- Materials Science
- Cosmochemistry
- Geology
Background:
- Carbyne, a novel allotrope of carbon, has been documented in scientific literature for nearly 15 years.
- Recent studies propose carbynes as potential interstellar dust components and carriers of presolar noble gases within meteorites.
Purpose of the Study:
- To critically reevaluate the existence of carbynes.
- To assess the role of carbynes and the mineral chaoite in extraterrestrial materials.
- To prompt a review of existing data concerning these carbon forms.
Main Methods:
- Review and reanalysis of existing experimental data and literature.
- Comparative analysis of properties attributed to carbynes and chaoite.
- Investigation of theoretical models supporting or refuting carbyne stability.
Main Results:
- The existence of carbynes and the mineral chaoite is currently under scrutiny.
- Previous data supporting their presence requires re-examination in light of new evidence and theoretical understanding.
- The role of these carbon allotropes in meteorites and interstellar dust is uncertain.
Conclusions:
- A comprehensive reevaluation of the evidence for carbynes and chaoite is necessary.
- Further research is required to confirm or refute their existence and properties.
- The scientific community should critically assess prior findings regarding these carbon forms.

01:12Carbon Skeletons
Life on Earth is carbon-based, as all macromolecules that make up living organisms contain carbon atoms. All organic compounds have a carbon backbone. Each carbon atom is tetravalent and can bond with four other atoms, making it an extraordinarily flexible component of biological molecules. Because carbon’s valence electrons are stable, it rarely becomes an ion. As the carbon chain increases in length, structural modifications such as ring structures, double bonds, and branching side chains...
03:02Organic Compounds
All living things are formed mostly of carbon compounds called organic compounds. The category of organic compounds includes both natural and synthetic compounds that contain carbon. Although a single, precise definition has yet to be identified by the chemistry community, most agree that a defining trait of organic molecules is the presence of carbon as the principal element, bonded to hydrogen and other carbon atoms. However, some carbon-containing compounds such as carbonates, cyanides, and...
01:14The Carbon Cycle
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.
02:10Carbocations
Carbocations are one of the reaction intermediates formed during several nucleophilic substitutions or elimination reactions. A carbocation is an electron-deficient species with the central carbon atom having six electrons and three bonded atoms. The central carbon in a carbocation is sp2 hybridized with trigonal planar geometry. It has an empty p orbital perpendicular to the plane of the structure that can accept electrons. Thus, carbocations act as strong electrophiles and may react with any...

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...

02:28Cycloalkanes
Cycloalkanes are saturated cyclic hydrocarbons with carbon atoms arranged in the form of rings. They have two fewer hydrogen atoms than the corresponding acyclic alkane; therefore, their general formula is CnH2n. The structural formulas of cycloalkanes are simplified using the line-angle representation. The regular polygons are used to represent the cycloalkane rings, with each side representing a carbon-carbon bond.
The IUPAC nomenclature of cycloalkanes follows similar rules that apply to...
