Chemistry - CHEMICAL BONDING Question with Solution | TestHub
Molecule in which both the lone pair of central atom are opposite to each other.
Options:(select one or more)
Answer:
Solution:
To find molecules where the lone pairs on the central atom are opposite to each other, we look at their VSEPR geometry:
XeF₄: Xenon has 2 lone pairs and 4 bond pairs (Square Planar). To minimize repulsion, the 2 lone pairs occupy opposite axial positions.
ICl₄⁻: Iodine has 2 lone pairs and 4 bond pairs (Square Planar). Like XeF₄, the 2 lone pairs are positioned opposite to each other.
ICl₃: Iodine has 2 lone pairs and 3 bond pairs (T-shaped). The lone pairs occupy equatorial positions at an angle of approximately , not opposite.
XeF₅⁻: Xenon has 2 lone pairs and 5 bond pairs (Pentagonal Planar). The 2 lone pairs occupy the axial positions, which are opposite to each other.
