Options

A. `XeO_(3)`
B. `XeO_(2)F_(2)`
C. `XeOF_(4)`
D. `XeF_(4)`

Answer

4

Explanation

It has zero dipole moment because it is square plannar:

`XeO_(3)` contains three `pi-`bonds, and the remaining four eletron pairs form a tetrahedron with one corner occupied by a lone pair of eletrons.
`XeO_(2)F_(2)` Is trigonal bipyramidal with one of the equatorial positions occupied by a lone pair.`XeOF_(4)` is octahedral with one of the corners occupied by a lone pair.
