Tetrafluoromethane, also known as carbon tetrafluoride or R-14, is the simplest perfluorocarbon (C F 4). As its IUPAC name indicates, tetrafluoromethane is the perfluorinated counterpart to the hydrocarbon methane .
Carbon tetrafluoride (tetrafluoromethane) Cerium tetrafluoride, CeF 4; Cobalt tetrafluoride, CoF 4; Curium tetrafluoride, CmF 4; Diboron tetrafluoride, B 2 F 4, a colorless gas; Dinitrogen tetrafluoride, N 2 F 4 (Tetrafluorohydrazine) Einsteinium tetrafluoride, EsF 4; Germanium tetrafluoride, GeF 4; Hafnium tetrafluoride, HfF 4; Iridium ...
The carbon–fluorine bond length is typically about 1.35 ångström (1.39 Å in fluoromethane). [1] It is shorter than any other carbon–halogen bond, and shorter than single carbon–nitrogen and carbon–oxygen bonds.
CHF 3 is used in the semiconductor industry in plasma etching of silicon oxide and silicon nitride.Known as R-23 or HFC-23, it was also a useful refrigerant, sometimes as a replacement for chlorotrifluoromethane (CFC-13) and is a byproduct of its manufacture.
The structure of organofluorine compounds can be distinctive. As shown below, perfluorinated aliphatic compounds tend to segregate from hydrocarbons. This "like dissolves like effect" is related to the usefulness of fluorous phases and the use of PFOA in processing of fluoropolymers. In contrast to the aliphatic derivatives, perfluoroaromatic ...
The structure of the tetrafluoroborate anion, BF − 4. Tetrafluoroborate is the anion BF − 4. This tetrahedral species is isoelectronic with tetrafluoroberyllate (BeF 2− 4), tetrafluoromethane (CF 4), and tetrafluoroammonium (NF + 4) and is valence isoelectronic with many stable and important species including the perchlorate anion, ClO −
Trichlorofluoromethane was first widely used as a refrigerant.Because of its high boiling point compared to most refrigerants, it can be used in systems with a low operating pressure, making the mechanical design of such systems less demanding than that of higher-pressure refrigerants R-12 or R-22.
