Final answer:
The correct name for the molecular compound SF5 is 'sulfur pentafluoride', following the standard prefix convention used in chemical nomenclature for nonmetals.
Step-by-step explanation:
The name of the molecular compound SF5 is d. sulfur pentafluoride. In molecular nomenclature, the prefix 'penta-' indicates that there are five atoms of the element present. Therefore, SF5 corresponds to sulfur pentafluoride. This is consistent with the convention of using prefixes in chemical nomenclature for covalent compounds to indicate the number of atoms of each element in the compound: mono- for one, di- for two, tri- for three, tetra- for four, penta- for five, hexa- for six, hepta- for seven, and so on.
