Interpretation:
The Lewis structures of SF4 and SF6 molecules needs to be determined by interpreting the polarity.
Concept introduction:
The Lewis structure of an organic compound represents the bonding of atoms with lone pairs (if any). It indicates the bonds with atoms and also arrangement of atoms in molecule. The polarity of molecule can be determined by the arrangements of bonded atoms in the molecule.

Answer to Problem 77SSC
Polar molecule
Non-polar molecule
Explanation of Solution
In the SF4 molecule, Satom contains 6 valence electrons and F has 7 valence electrons. The total number of valence electron can be determined in it as follows:
Number of valence electron = Number of atom S (valence electron in S) + Number of atom F (valence electron in F) =
Hence the Lewis structure must be:
Since the standard geometry must be trigonal bipyramid yet the geometry changes to see-saw due to presence of one lone pair on S atom.
Since the polarity directions are towards F atom therefore overall it is a polar molecule.
In the SF6 molecule, S atom contains 6 valence electrons, and F has 7 valence electrons. The total number of valence electron can be determined in it as follows:
Number of valence electron = Number of atom S (valence electron in S) + Number of atom F (valence electron in F) =
Hence the Lewis structure must be:
Due to symmetrical structure of molecule it is non-polar molecule.
Thus,
