The correct name of the compound with the chemical formula SF4 is sulfur tetrafluoride.
To understand why, let’s break down the chemical formula. The ‘S’ in SF4 stands for sulfur, and the ‘F’ represents fluorine. The subscript ‘4’ indicates that there are four fluorine atoms bonded to one sulfur atom in the molecule.
In chemical nomenclature, prefixes are used to indicate the number of atoms present in a compound. The prefix ‘tetra-‘ means four, which applies here for the four fluorine atoms. Therefore, the full name is sulfur tetrafluoride. The other options can be dismissed as they either imply incorrect quantities of sulfur or fluorine or refer to different compounds entirely.
