Kabọn Tetrafluoride
Tetrafluoromethane, nke a makwaara dị ka carbon tetrafluoride, bụ fluorocarbon kachasị mfe (CF4). O nwere ike njikọ dị elu n'ihi ọdịdị nke njikọ carbon-fluorine. Enwere ike ịkọwa ya dị ka haloalkane ma ọ bụ halomethane. N'ihi ọtụtụ njikọ carbon-fluorine, na electronegativity kachasị elu nke fluorine, carbon dị na tetrafluoromethane nwere nnukwu ụgwọ akụkụ dị mma nke na-eme ka njikọ carbon-fluorine anọ sie ike ma belata site n'inye njirimara ionic ọzọ. Tetrafluoromethane bụ gas griinhaus siri ike.
