Hence, the molecular shape for SeF4 is see-saw and its electron geometry is trigonal bipyramidal.

How many valence electrons do you have left for SeF4?

You’ll have a pair of electrons left over after filling octets of the F atoms. You can put these on the central Se atom. The Lewis structure for SeF4 has 34 valence electrons available to work with.

Does SeF4 obey octet rule?

From the structure “Se” have four bonds. And central atom “ Se” surrounded by eight bonding electrons and one pair of nonbonding electrons . Hence ,SeF4 does not obey the octet rule.

Does SeF4 have a tetrahedral structure?

Applying VSEPR rules to minimise repulsion among lone pairs, bond pairs, lone pair-bond pairs, we see that the repulsion is minimum iff lone pairs are anti to one another and the fluorine atoms occupy Equatorial position. Hence, the fine geometry or the shape of the compound is Square planar. It is tetrahedral.

Is SeF4 nonpolar or polar?

Yes,selenium tetrafluoride that means SeF4 is a polar molecule because it is of AB4E type molecule. Hence it’s geometry is trigonal bipyramidal and shape is see saw.

Does SeF4 and CH4 have same shape?

c SeF4 and CH4 have same shape.

What was the molecular geometry for scl6?

The electron pair geometry and molecular geometry are both octahedral. All bond angles are 90⁰. An example is sulfur hexachloride (SCl6).
