Carbon Tetrafluoride
Tetrafluoromethane, wanda aka fi sani da carbon tetrafluoride, shine mafi sauƙin fluorocarbon (CF4). Yana da ƙarfin haɗin kai mai yawa saboda yanayin haɗin carbon-fluorine. Hakanan ana iya rarraba shi azaman haloalkane ko halomethane. Saboda yawan haɗin carbon-fluorine, da kuma mafi girman electronegativity na fluorine, carbon a cikin tetrafluoromethane yana da babban caji mai kyau wanda ke ƙarfafawa da rage haɗin carbon-fluorine guda huɗu ta hanyar samar da ƙarin halayen ionic. Tetrafluoromethane iskar gas ce mai ƙarfi ta greenhouse.
A wasu lokutan ana amfani da Tetrafluoromethane a matsayin na'urar sanyaya iska mai ƙarancin zafi. Ana amfani da shi a cikin ƙirar lantarki kawai ko kuma a haɗa shi da iskar oxygen a matsayin na'urar cire sinadarin plasma don silicon, silicon dioxide, da silicon nitride.
