which of the following compouds of fluorine is used for dielectrics?

Options

A. `UF_(6)`
B. `SF_(6)`
C. `NaF`
D. `SnF_(2)`

Answer

2

Explanation

Fluorine is used mainly for the manufacture of `UF_(6)` for nuclear power generation and `SF_(6)` for dielectrics. The important organic chemicals derived from` HF` are the chlorofluorocarbons, and polytetrafluoroethylene (Teflon).
Chlorofluorocarbons know as freons are used as refrigerants (however, these are being phased out in favour of chlorofluor hydrocarbons ) and in aerosols and artificial blood.
Minor uses of `HF` are in the glass industry as an etching agent and in the manufacture of fluoride salts. Prominent among the fluorides is `NaF` used for the fluoridation of water, one part per million level of fluoride in drinking water prevents tooth decay. `SnF_(2)` is used in fluoride tooth paste.
