Write preparation of : (i) Xenon - Fluorine compounds (ii) Xenon - Oxygen compounds

Answer»

Solution :Xenon - Fluorine compounds : Xenon forms three binary fluorides, `XeF_2, XeF_4` and `XeF_6` by the direct reaction of ELEMENTS under appropriate experimental conditions.
`UNDERSET("excess")(Xe(g)) + F_(2)(g) overset(673 K, 1bar)to XeF_(2)(s)`
`underset(1:5 "ratio")(Xe(g) + 3F_(2)(g) overset(573 K)/(50-70 "BAR")to XeF_(6)(s)`
`XeF_6` can also be prepared by the interaction of `XeF_4` and `O_(2)F_(2)` at 143 K.
`XeF_(4) + O_(2)F_(2) to XeF_(6) + O_(2)`
Xenon-Oxygen compounds : Hydrolysis of `XeF_4` and `XeF_6` with water gives `XeO_(3)`
`6XeF_(4) + 12H_(2)O to 4Xe + 2XeO_(3) + 24HF + 3O_(2)`
`XeF_(6) + 3H_(2)O to XeO_(3) + 6HF`
Partial hydrolysis of `XeF_6` gives oxyfluorides,
`XeF_(6) + H_(2)O to XeOF_(4) + 2HF`
`XeF_(6) + 2H_(2)O to XeO_(2)F_(2) + 4HF`
