`F_(2)` is formed by reacting `K_(2) MnF_(6)` with

A

`SbF_(5)`

B

`MnF_(3)`

C

`KSbF_(6)`

D

`MnF_(4)`

Text Solution

Verified by Experts

The correct Answer is:
A
`K_(2)MnF_(6)+2SbF_(5)rarr2KsbF_(6)+MnF_(3)+(1)/(2)F_(2)` In this reaction, the stronger Lewis acid `SbF_(3)` displaces the weaker one, `MnF_(4)` from its salt. `MnF_(4)` is unstable and readily decomposes to give `MnF_(3)` and fluorine.
