Question

Assertion :Fluorides of Xe are thermodynamically stable. Reason: They are endothermic compounds.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is true but Reason is false
• D. Assertion is false but Reason is true

Answer 1

The correct option is C Assertion is true but Reason is false

All three fluorides of xenon, $Xe{F}_2$, $Xe{F}_4$ and $Xe{F}_6$ are thermodynamically stable at room temperature.

All the reaction to form Xenon fluorides are exothermic, releasing an energy.

Example:

$Xe+2F_2⟶Xe{F}_4$ reaction is exothermic, releasing an energy of 251 kJ/mol of xenon.
