Pick out the incorrect statement for `XeF_(4)`.

Options

A. `XeF_(4)` disproportionate violently with water
B. It is used as fluorinating agent
C. It has octahedral structure (or geometry)
D. It oxidises `l^(-)` to `l_(2)`

Answer

C

Explanation

According to VSEPR theory, six electrons pairs form an octahedron with two position occupied by lone pairs. This results in square planar structure of `XeF_(4)`. So, (c) is incorrect other statement are correct.
`3XeF_(4)+6H_(2)Oto2Xe+XeO_(3)+12HF+(3)/(2)O_(2)`
`XeF_(4)` is reduced to Xe and also oxidised to `XeO_(3)`.
(i) `XeF_(4)+2SF_(4)toXe+2SF_(6)`
(ii) `3XeF_(4)+2Pt to 3Xe+2PtF_(6)`
(iii) `XeF_(4)+C_(6)H_(6)toXe+C_(6)H_(5)F+HF_(3)`
`XeF_(4)+4Kl to4KF+Xe+2l_(2)`.
