Carbon Tetrafluoride
Tetrafluoromethane, quae carbo tetrafluoride nota est, fluorocarbon simplicissimum est (CF4).Maximum vinculum habet vim ex natura vinculi carbonis-fluorini.Potest etiam collocari ut haloalkane vel halomethane.Propter vincula carbon-fluorinorum multiplex et summa electronegativitas fluorini, carbo in tetrafluoromethane notabile crimen partiale habet positivum, quod confirmat et minuit vincula quattuor carbon-fluorinis, ionicam indolem adiectis praebendo.Tetrafluoromethane est potentior CONSERVATORIUM gas.
Tetrafluoromethane interdum adhibetur ut refrigerans temperatus humilis.Adhibetur in sola microfabricatione electronicis vel in compositione cum oxygenio sicut plasma etcantis siliconis, dioxidis pii, et nitridis siliconis.
