A

NaF and `OF_2`

B

`NaF _ O_3`

C

`O_2 and O_3`

D

`NaF + O_2`

Text Solution

Verified by Experts

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