Fluorine is obtained by the interaction ...

Fluorine is obtained by the interaction of `K_2MnF_6` with Lewis acid `SbF_5` because of the

A

Acidolysis of `MnF_4`

B

Decomposition of `MnF_4`

C

Ionisation of `MnF_4`

D

Decomposition of `SbF_6`

Text Solution

Verified by Experts

The correct Answer is:
B
`({:(2K_2MnF_6+4SbF_5 to, 4KSbF_6+ 2MnF_4),(2MnF_4 to, 2MnF_3 + F_2):})/ul(2K_2MnF_6 +4SbF_5 to 4KSbF_6+2MnF_3 +F_2)`
Here stronger Lewis acid `SbF_5` displaces weaker acid `MnF_4` from `K_2MnF_6`. Initially formed `MnF_4` being unstable decomposes to `MnF_3` and `F_2`.
