  1. Question 1

    Q1. A mixture of Xenon and Fluorine in a 1:2 ratio is heated in a sealed nickel vessel at 400 degrees Celsius. Which noble gas compound is synthesized?

    • A) Xenon tetrafluoride (XeF4)
    • B) Xenon hexafluoride (XeF6)
    • C) Xenon trifluoride (XeF3)
    • D) Xenon difluoride (XeF2)

    Answer: Xenon difluoride (XeF2)

    Explanation: Xenon reacts with fluorine in a 1:2 ratio at 400 degrees Celsius and 6 atm to produce XeF2; higher ratios produce XeF4 or XeF6.
