1.	What is teflon ? How is it prepared ?
Answer» Solution :Teflon is polytetrafluoroethylene. It is PREPARED by the ACTION of chloroform with antimony trifluoride and hydrofluoric acid, followed by vinyl polymerisation. `CHCl_3 underset(HF)overset(SbF_3)(rarr)CHF_2Cl underset(-HCl)overset(800^@ C)(rarr)CF_CF_2` `nCF_2 = CF_2 rarr [-CF_2 - CF_2]_n`.
