Question:

XeF6 on partial hydrolysis with water produces a compound X. The same compound X is formed when XeF6 reacts with silica. The compound X is:

XeF2

XeO3

XeOF4

XeF4

Solution:

Partial hydrolysis of XeF6 gives XeOF4 (compound X)
XeF6 + H2O → XeOF4 + 2HF
XeF6 reacts with silica SiO2 to form XeOF4 (compound X)
2XeF6 + SiO2 → 2XeOF4 + SiF4
