Question

Explain the reactivity of Group 18 towards halogens.

Answer 1

• Group 18 elements are chemically inert. 
• However, inert elements like krypton and xenon react directly with fluorine under appropriate conditions to give their fluorides. 

For example,

• The xenon fluorides XeF₂, XeF₄ and XeF₆ are colourless crystalline solids which sublime at 298 K.
• These fluorides are strong fluorinating agents.
