In which of the following molecule/ion all the bonds are not equal?

A

`SF_4`

B

`SiF_4`

C

`XeF_4`

D

`BF_4`

Text Solution

Verified by Experts

The correct Answer is:
A
`SF_4` molecule is triangular bipyramidal, both `BF_(4_^(-) and SiF_(4)` are tetrahedral, whereas `XeF_(4)` has octahedral arrangement of lone pairs and is square planar in geometry. In tetrahedral and square planar geometries, all the bonds are equal. In triangular bipyramidal geometry, the two axial bonds (155 pm) are smaller than the remaining two equatorial bonds (165 pm).
