Xenon fluorides are all extermely strongA. reducing agentB. oxidizing

1.	Xenon fluorides are all extermely strongA. reducing agentB. oxidizing agentC. flourinating agentsD. both (2) and (3)
Answer» Correct Answer - 4 They are all extremely strong oxidizing and fluorinating agents. They react quantitatively with hydrogen as follows: `XeF_(2)+H_(2)rarr2HF+Xe` `XeF_(4)+2H_(2)rarr4HF+Xe` `XeF_(6)+3H rarr 6HF+Xe` They oxidizes chloride to chlorine iodide to cerium `(+3)` to cerium `(+4)`: `XeF_(2)+2HCl rarr Cl_(2)+2HF+Xe` `XeF_(4)+4Kl rarr 2I_(2)+4KF+Xe` `SO_(4)^(2-)+XeF_(2)+Ce_(2)(SO_(4))_(4)rarr2Ce(SO_(4))_(2)+F_(2)+Xe` They fluorinate compounds: `XeF_(4)+C_(6)H_(6)rarrC_(6)H_(5)F+Xe+HF` `XeF_(4)+Pt rarr PtF_(4)+Xe` `XeF_(4)+2SF_(4)rarr2SF_(6)+Xe`
