Which of the following fluorides of Xe has zero dipole moment ?

Options

A. `XeF_(2)`
B. `XeF_(3)`
C. `XeF_(4)`
D. `XeF_(6)`

Answer

C

Explanation

In `XeF_(4)`, the four fluorine atoms are present at the corners of a square plane and two lone pair are present at axial positions. All the individual bond moments in such an arragement cancel out, as a result, the molecule has zero dipole moment.
