Chemistry Question on p -Block Elements

Xenon hexafluoride on partial hydrolysis produces compounds ?X? and ?Y?. Compounds ?X? and ?Y? and the oxidation state of Xe are respectively :

A

XeO2(+4)XeO_2(+4) and XeO3(+6)XeO_3(+6)

B

XeOF4(+6)XeOF_4(+6) and XeO3(+6)XeO_3(+6)

C

XeO2F2(+6)XeO_2F_2(+6) and XeO2(+4)XeO_2(+4)

D

XeOF4(+6)XeOF4(+6) and XeO2F2(+6)XeO2F2(+6)

Answer

XeOF4(+6)XeOF4(+6) and XeO2F2(+6)XeO2F2(+6)

Explanation

Solution

The reactions involved are as follows:

XeF6+H2OXe+6OF4(X)+2HFXeF _{6}+ H _{2} O \rightarrow \underset{( X )}{\overset{+6}{Xe} OF _{4}}+2 HF
XeOF4(X)+H2OXe+6O2F2(Y)+2HF\underset{(X)}{XeOF _4}+ H _{2} O \rightarrow \underset{( Y )}{\overset{+6}{Xe} O _{2} F _{2}}+2 HF
