Because the central Xenon atom has two lone pairs of valence electrons of a molecule, the molecular geometry will help with the repulsion.
Polar molecules have polar covalent bonds or ionic bonds.
A water molecule, because of its shape, is a polar molecule.
Factors influencing the Polarity of XeF4 molecule A number of considerations go into determining whether the XeF4 molecule is polar or non-polar.
This is a symmetrical structure where all Xe-F polar bonds in the square planar arrangement cancel.
Well the reason behindis the electronegativity of elements.
