What is the shape of a molecule of sulfur tetrafluoride?

Answer 1

Tetrahedral. Actually, the molecular shape or geometry is called see-saw. There are five groups around the central sulfur which would make it trigonal bipyramidyl but one of these groups is a pair of electrons which does not contribute to the shape of the molecule. This lone pair is in the three membered ring in order to increase its separation from two of the fluorine-sulfur bonds.

Answer 2

The shape of a sulfur tetrafluoride molecule is trigonal bipyramidal, with the central sulfur atom surrounded by five regions of electron density. There are four fluorine atoms bonded to the central sulfur atom, along with one lone pair of electrons.
