The reaction of solid X e F 2 with A s F 5 in 1:1 ratio affords

Options

  1. AX e F 4 and A s F 3
  2. BX e F 6 and A s F 3
  3. CX e F + A s F 6 -
  4. D[ X e 2 F 3 ] + [ A s F 6 ] -

Correct answer

C. X e F + A s F 6 -

Step-by-step solution

X e F 2 (Xenon difluoride) acts as a fluoride donor and thus, forms complex when mixed with covalent pentafluorides like A s F 5 . X e F 2 1 + A s F 5 1 → X e F + A s F 6 -
