Fluoromethylidyne
Encyclopedia
Fluoromethylidyne is not a stable chemical species but a metastable radical
containing one highly reactive carbon atom bound to one fluorine atom with the formula
CF. The carbon atom has a lone-pair and a single unpaired (radical) electron in the ground state
.
Ground-state fluoromethylidyne radicals can be produced by the ultraviolet
photodissociation
of dibromodifluoromethane
at 248 nanometer wavelength.
It readily and irreversibly dimerises to difluoroethyne, also known as di- or perfluoroacetylene, or di- or perfluoroethylyne. Under certain conditions it can polymerise (trimerise) to hexafluorobenzene

Radical (chemistry)
Radicals are atoms, molecules, or ions with unpaired electrons on an open shell configuration. Free radicals may have positive, negative, or zero charge...

Ground state
The ground state of a quantum mechanical system is its lowest-energy state; the energy of the ground state is known as the zero-point energy of the system. An excited state is any state with energy greater than the ground state...

Ultraviolet
Ultraviolet light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 400 nm, and energies from 3 eV to 124 eV...
photodissociation
Photodissociation
Photodissociation, photolysis, or photodecomposition is a chemical reaction in which a chemical compound is broken down by photons. It is defined as the interaction of one or more photons with one target molecule....

Dibromodifluoromethane
Dibromodifluoromethane is a mixed halomethane. It is a colorless non-flammable liquid.Along with Halons 1211, 2402, and 1301, it is the most effective fire extinguishers, however, also the most toxic one.It is a class I ozone depleting substance ....

Hexafluorobenzene
Hexafluorobenzene, HFB, , or perfluorobenzene is an organic, aromatic compound. In this derivative of benzene all hydrogen atoms have been replaced by fluorine atoms. The technical uses of the compound are limited, although it is recommended as a solvent in a number of Photochemical reactions...
