Fluorine reacts with cold dilute NaOH to give

A

NaF and `O_2`

B

NaF and `OF_2`

C

NaF and `H_2O_2`

D

NaF, `H_2O_2 and F_2O`.

Text Solution

Verified by Experts

The correct Answer is:
B
`2F_2+underset("Cold, dilute")(2NaOH)to OF_2 + 2NaF +H_2O`
However with conc. NaOH, `O_2` is formed
`2F_2 + underset("conc.")(4NaOH) to 4NaF + 2H_2O+O_2`
