Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion XeF6 reacts with silica or glass. Because of the stepwise reaction which finally produces the dangerous XeO3,XeF6 cannot be handled in glass or quartz apparatus. 2XeF6+SiO2→2XeOF4+SiF4 2XeOF4+SiO2→2XeO2F2+SiF4 2XeO2F2+SiO2→2XeO3+SiF4
