Which is incorrect statement for XeF_2?

Answer»

It has linear structure
It is hydrolysed rapidly in aqueous solution of a base
It oxidizes `CI^(-) and I^(-)" to "Cl_2 and I_2` respectively
It cannot act as `F^(-)` donor.

Solution :It act as a `F^(-)` donor and forms complexes with covalent fluroides like `PF_(6), AsF_(6) and SbF_(5)`.
`XeF_(2)+PF_(5) to [XeF]^(+) [PF_(6)]^(-)`
(a) The five electron pairs form trigonal bipyramidal with three lone pairs in equatoríal positions. HENCE, the structure of `XeF_(2)`, becomes linear in ACCORDANCE with VSEPR theory.
