What is the correct name for the molecular compound with the formula SF_6?
A
hexasulfur fluoride
B
sulfur(VI) fluoride
C
sulfur hexafluoride
D

Verified step by step guidance1
Identify the elements present in the compound SF_6: sulfur (S) and fluorine (F).
Recognize that SF_6 is a molecular compound composed of nonmetals, so the naming follows the rules for covalent compounds.
Use prefixes to indicate the number of atoms of each element: 'hexa-' means six fluorine atoms, and since there is only one sulfur atom, no prefix is needed for sulfur.
Combine the element names with the appropriate prefixes: 'sulfur' for S and 'hexafluoride' for six fluorine atoms.
Put the name together as 'sulfur hexafluoride' to correctly name the compound SF_6.
