1.	How many of the following statement are correct ? (1) CF_(4) can be prepared by reaction between SiC and F_(2). (2) In SiF_(4) Si-F observed bond length is shorter than actual Si-F bond length (3) (C_(2)F_(4))_(n) is known as PTFE. (4) C Cl_(4) react with Anyelrony HF, gives Chloro Flouro carbon (C Cl_(2)F_(2)) (5) C Cl_(4) can hydrolysis under super heating conditious. (6) Hydrolysis of SiF_(4) is not complete of SiF_(4) is partially hydrolysis.
Answer» SOLUTION :(1)`SiC+F_(2)to SiF_(4)+CF_(4)` (2)Because of `dpi-ppi` BACK bonding in `SiF_(4)` (3)`PTFE=` Poly tetra flouro ethene (4)`C Cl_(4) +HF to C Cl_(2)F_(2)+HCl` (5)`C Cl_(4)underset("Super heating (steam)")overset(+H_(2)O) to COCl_(2)+HCl` (6)`SiF_(4)+F^(-)to [SiF_(6)]^(-2)` (`F^(-)` forms in `I^(ST)` staoe gtdriksus if `Si F_(4))`
