How are X e O 3 and X e O F 4 prepared?
Solution:
Hydrolysis of X e F 4 and X e F 6 with water gives X e F 3 .
6 X e F 4 + 12 H 2 O → 4 X e + 2 X e O 3 + 24 H F + 3 O 2 X e F 6 + 3 H 2 O → X e O 3 + 6 H F
Partial hydrolysis ofX e F 6 gives oxyfluorides, X e O F 4 and X e O 2 F 2 .
X e F 6 + H 2 O → X e O F 4 + 2 H F
X e F 6 + 2 H 2 O → X e O 2 F 2 + 4 H F
Partial hydrolysis of
