Understanding the molecular structure of a compound can help determine the polarity, reactivity, phase of matter, color, magnetism, as well as the biological activity. Same goes for the SF4 molecule. The molecular geometry of this molecule is square planar as this how the different lone pairs of both atoms adjust with one another. Also, as the shape of the molecule is like a see-saw, two fluorine atoms can cancel out each other’s dipole moment, but the rest two can’t due to the electrons’ arrangement. This arrangement of electrons around the atom and hybridized orbitals leads to the sp3d hybridization. Molecular structure, which refers only to the placement of atoms in a molecule and not the electrons, is equivalent to electron-pair geometry only when there are no lone electron pairs around the central atom. Their bond dipoles do not cancel, so the molecule is polar. The idea of a correlation between molecular geometry and number of valence electron pairs (both shared and unshared pairs) was originally proposed in 1939 by Ryutaro Tsuchida in Japan, and was independently presented in a Bakerian Lecture in 1940 by Nevil Sidgwick and Herbert Powell of the University of Oxford. A molecule has 2 double bonds on the central atom and no lone pairs. What scientific concept do you need to know in order to solve this problem? The SF4 hybridization structure looks as given below.

Also Know, what is the hybridization of sf4 molecule? molecular shape is a see-saw, because of the presence of 1 lone pair. This electron arrangement is called ‘Trigonal Bipyramidal’. Thus, the S atom is bonded to 4 fluorine atom and has 1 lone pair. Due to this, the hybridization is sp. The reason behind this is that the lone pair prefers one of the equatorial positions. It is nonpolar If the charge distribution is symmetric. The S atom in the SF4 is bonded to 4 Fluorine atoms and has 1 lone pair (S has 6 valence electrons; 4 of them undergo bonding with 4 Fluorine atoms while the other 2 remains as a lone pair on S atom). During SF4 formation, the sulfur atom will produce bonds with each of fluorine atoms where 8 of valence electrons are used. The equatorial fluorine atoms have 102° bond angles instead of the actual 120° angle. The molecular geometry is described only by the positions of the nuclei, not by the positions of the lone pairs. The lone pair on the central atom leads to the change in the bond angles from 120 degrees to 102 degrees for equatorial fluorine atoms and 173 degrees instead of 180 degrees for axial fluorine atoms. (polar Or Non Polar) This problem has been solved! Besides, two electrons will be placed as a lone pair in the sulfur atom. SF4 molecular geometry is seesaw with one pair of valence electrons.
