Perfluorocarbons (PFCs):
Perfluorocarbons (CnF2n+2) are acquired by controlled fluorination of vapourized alkanes diluted along with nitrogen gas in the existence of a catalyst.
Perfluorocarbons are non-polar, non-corrosive, colourless, extremely stable, odourless, non-toxic, unreactive gases and non-flammable, solids and liquids. These are stable also to ultraviolet radiations and other ionising radiations and hence, they do not detect the ozone layer such as freons.
The correct electronic configuration of Ti(Z= 22) atom is: (1) 1s 2 , 2s 2 , 2p 6 , 3p 6 , 4s 2 , 3d 2 , (2) 1s 2, 2s 2 , 2p 6 , 3p 6 , , 3d 4 , (3) 1s 2 , 2s
