electron pair geometry: octahedral
molecular geometry: octahedral
IF6+ cation has no lone pairs, the IF6- anion has one lone pair. SF6 has no lone pairs.
In sulfur hexafluoride (SF6), the molecular geometry is octahedral. The approximate bond angles between the fluorine atoms are 90 degrees. Additionally, the angles between the axial and equatorial fluorine atoms are 180 degrees. Overall, the symmetrical arrangement ensures that all fluorine atoms are evenly spaced around the central sulfur atom.
SeF6 is a regular octahedron , all bond angles are 90 degrees
Selenium hexafluoride.
Selenium hexafluoride
CSe2 has Lewis structure like this: Se=C=Se (here are valence e- around the Se too, but no need to worry about these), Since it is considered that there are 2 bonds the shape would be linear. Linear corresponds to "sp" hybridization
NO. SiF4 is a tetrahedral molecule. It has one F on top and the other three as a base for a tetrahedral structure. F ! dipole is upwards for this F. Si resultant dipole is downwards for the 3 F's / ! ) F F F so they cancel each other. Therefore the dipole moment is 0.
This compound is called selenium hexafluoride.
