Which of the following fluoride of xenon has zero dipole moment?
Options
- AX e F 3
- BX e F 4
- CX e F 6
- DX e F 2
Correct answer
B. X e F 4
Step-by-step solution
In X e F 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.
