Super-Tricks to Remember all Reactions of Group-18 elements 🔥 | Xenon Chemistry by IITian Explains

Hello Guys, In this Lecture, we are going to discuss a very important topic from Group 18 elements for Jee Mains, Advanced , NEET and AIIMS.
In 1962, Neil Bartlett predicted that xenon should react with platinum hexafluoride He was the first to prepare a compound of xenon, called xenon hexafluoridoplatinate (V).Later many compounds of xenon were synthesised, including fluorides, oxides and oxy -fluorides
Methods to prepare xenon-fluorine compounds:
Xenon directly reacts with fluorine to form a binary fluoride, which may be xenon di fluoride, xenon tetra fluoride or xenon hexafluoride. The product depends on the ratio in which xenon and fluorine reacts.
Xenon and fluorine in the ratio of 2:1 heated at 673 K at 1 bar pressure give xenon di fluoride.
Xenon and fluorine in the ratio 1:5 heated at 873 K at 7 bar pressure give xenon tetra fluoride.
Xenon and fluorine in the ratio 1:20 heated at 573 K at 60-70 bar pressure give xenon hexafluoride.
Xenon hexafluoride can also be obtained by the reaction of xenon tetra fluoride and dioxygen difluoride at 143 K.
Structural aspects of the fluorides of xenon:
Structure of XeF2:
The central atom, xenon, in XeF2 undergoes sp3d hybridisation.
Xenon di fluoride has 5 electron pairs. Of these, 3 are lone pairs and 2 are bond pairs
The structure of xenon di fluoride is linear due to the presence of the 3 lone pairs of electrons on the central xenon atom.
Structure of XeF4:
The central atom, xenon, in XeF4 undergoes sp3 d2 hybridisation.
It has six electron pairs. Of these 4 are bond pairs and 2 are lone pairs.
The structure of xenon di fluoride is square planar due to the presence of the 2 lone pairs of electrons on the central xenon atom.
Structure of XeF6:
The central atom, xenon, in XeF6 undergoes sp3 d2 hybridisation.
It has 7 electron pairs. Of these 6 are bond pairs and 1 is a lone pair.
The structure of xenon hexafluoride is distorted octahedral owing to the presence of the single lone pair of electrons on the central xenon atom.
