How are `XeO_(3)` and `XeOF_(4)` prepared ?

Text Solution

Verified by Experts

Hydrolysis of `XeF_(4) and XeF_(6)` with water gives `XeO_(3)`
`6 XeF_(4) + 12 H_(2) O rarr 4 Xe + 2 XeO_(3) + 24 HF + 3 O_(2)," "XeF_(6) + 3H_(2)O rarr XeO_(3) + 6HF`
On the other hand, partial hydrolysis of `XeF_(6)` gives `XeOF_(4)`.
`XeF_(6) + H_(2)O rarr XeOF_(4) + 2HF`
