What happens when:

(a) PCl5 is heated?


(b) XeF2 reacts with PF5?


(a) When heated, PCl5 sublimes but decomposes on stronger heating.


PCl5 + Heat→ PCl3 + Cl2


(b) Xenon fluorides react with fluoride ion acceptors to form cationic species and fluoride ion donors to form fluoro anions


SO when XeF2 reacts with PF5, the following reaction takes place


XeF2+ PF5→ [XeF]+[PF6]-
