Q29 / 90 · JEE Main 2018 (15 Apr) · Chemistry

Xenon hexafluoride on partial hydrolysis produces compounds 'X' and 'Y' and the respective oxidation states of Xe are:

  • A
    XeOF2 (+4) and XeO3 (+6)
  • B
    XeOF4 +6 and XeO3 (+6)
  • C
    XeO2F2 (+6) and XeO2 (+4)
  • Correct answer
    D
    XeOF4 (+6) and XeO2F2 (+6)

Solution

Xenon hexafluoride on partial hydrolysis produces compounds XeOF4​ and XeO2F2​. In the compounds, XeOF4 and XeO2F2​, the oxidation states of Xe are +6 and +6 respectively.

XeF6 ​+ H2O  → XeOF4 ​+ 2HF

XeOF4 ​+ H2O  → XeO2F2 ​+ 2HF

Figure

Hence, the correct answer is option: 'D'.
