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 b

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.
