Answers
Answer:
ANSWER
The central iodine atom in IF
3
has 3 bond pairs and 2 lone pairs of electrons. It undergoes sp
3
d hybridisation which results in trigonal bipyramidal (T-shaped) geometry.
The central iodine atom in IF
5
has 5 bond pairs and 1 lone pair of electrons. It undergoes sp
3
d
2
hybridisation which results in octahedral (square pyramidal) geometry.
The central iodine atom in IF
7
has 7 bond pairs and 0 lone pairs of electrons. It undergoes sp
3
d
3
hybridisation which results in pentagonal bipyramidal geometry.
The ionic species are both isoelectronic and isostructural to XeF2 and XeF4
The hybridization and the structure of IF₂⁻ are sp³d and linear in geometry.
The hybridization and the structure of XeF₂ are sp³d and linear in geometry.
Hence, both IF₂⁻ and XeF₂ are isoelectronic and isostructural.
The hybridization and the structure of IF₄⁻ are sp³d² and square planar in geometry.
The hybridization and the structure of XeF₄ are sp³d² and square planar in geometry.
Hence, both IF₄⁻ and XeF₄ are isoelectronic and isostructural.
