Q.
Which of the following fluoride of xenon has zero dipole moment?
NTA AbhyasNTA Abhyas 2020The p-Block Elements - Part2
Solution:
In $XeF_{4}$ , the four fluorine atoms are present at the corners of a square plane and two lone pairs are present at axial positions. All the individual bond moments in such an arrangement cancel out, as a result, the molecule has zero dipole moment. Rest other are polar.
