Methane tetrafluoride

Representing a two electron covalent bond by a dash (—) the Lewis structures for hydrogen fluoride fluorine methane and carbon tetrafluoride become... 

Now let s apply the Lewis model to the organic compounds methane and carbon tetrafluoride. 

Caibon has eight electrons in its valence shell in both methane and carbon tetrafluoride. By forming covalent bonds to four other atoms, carbon achieves a stable electron configuration analogous to neon. Each covalent bond in methane and carbon tetrafluoride is quite strong—comparable to the bond between hydrogens in Fl2 in bond dissociation energy.

The anodic oxidation of alkanes on a platinum anode in anhydrous hydrogen fluoride19 at low potentials is accompanied by exhaustive fluorination, with all of the hydrogen atoms being replaced by fluorine. Thus, the major fluorination products of methane and propane are carbon tetrafluoride and octafluoropropane, respectively. 

Pcrfluorobenzophenone and its 4,4 -dinitro derivative react with sulfur tetrafluoride relatively rapidly at 220 - 240X to give good yields of pcrfluoro(diphenylmethane) (6a) and perfluoro-[bis(4-nitrophenyl)methane] (6b).99... 

Methane22 over cobalt(III) fluoride at 205L C gives fluoromethane (10.5%), difluoro-methane (27%), trifluoromethane (40%), and carbon tetrafluoride (8%). 

The photolysis of trifluoroacetone with light of wavelength 3130 A. has been studied by Sieger and Calvert.48 The products of decomposition were shown to be carbon monoxide, methane, ethane, 1,1,1-trifluoro-ethane, and hexafluoroethane. There was no indication of the presence of carbon tetrafluoride or methyl fluoride. The quantum yield of all products was low at low temperature and it is assumed that the excited molecule of trifluoroacetone has an appreciable lifetime and may be deactivated by collision before decomposition can occur. This contention is supported by the decrease in the quantum yields observed when foreign gases such as carbon dioxide are added, and by the fall in quantum yields with increase in trifluoroacetone concentration.

When an excess of tetramethylstannane was condensed on cis- or rran.s-hydroxy methoxy tellurium tetrafluoride and the mixture warmed to 20°, methane was liberated. Stirring the mixture for two hours and briefly heating it to 40°, produced, after evaporation of the excess tetramethylstannane, the colorless, low melting cis- or trans-methoxy trimethylstannoxy tellurium tetrafluoride in quantitative yields. ... 

Cis- and ranj-hydroxy methoxy tellurium tetrafluoride reacted stereospecifically with chlorotrimethylsilane tetramethylstannane, and boron trichloride with elimination of hydrogen chloride or methane. The compounds obtained are trimethylsiloxy methoxy tellurium tetrafluoride trimethylstannoxy methoxy tellurium tetrafluoride, and boron tris[methoxo(oxo)tetrafluorotellurate (VI)]... 

The Group IVA atom contributes four electrons to the bonding in a tetrahedral AB4 molecule, and the other four atoms contribute one electron each. The Lewis formulas for methane, CH4, and carbon tetrafluoride, CF4, are typical.
