With cold and dilute sodium hydroxide fluorine reacts to give

A

`NaF` and `OF_(2)`

B

`NaF+O_(3)`

C

`O_(2)` and `O_(2)`

D

`NaF+O_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Fluorine is the most electronegative element. It does not form oxyfluoxide like other halogens. If reacts with `NaOH` to form sodium fluoride and oxygen fluoride.
`2NaOH+2F_(2)rarr2NaF+OF_(2)+H_(2)O`
