Q. Which among the following species has unequal bond lengths?
Solution:
Species
Hybridisation
Bond length
$BF_4^{⊝ }$
$sp^3$ (Tetrahedral)
All bond lengths equal
$XeF_4$
$sp^3d^2$ (sq. planar)
All bond lengths equal
$SF_4$
$sp^3d$ (see - saw)
axial bond length > equitorial bond length
$SiF_4$
$sp^3$ (Tetrahedral)
all bond lengths equal
Species | Hybridisation | Bond length |
---|---|---|
$BF_4^{⊝ }$ | $sp^3$ (Tetrahedral) | All bond lengths equal |
$XeF_4$ | $sp^3d^2$ (sq. planar) | All bond lengths equal |
$SF_4$ | $sp^3d$ (see - saw) | axial bond length > equitorial bond length |
$SiF_4$ | $sp^3$ (Tetrahedral) | all bond lengths equal |
