What is the chemical name of the covalent compound SF6?

A.

monosulfur hexafluoride

B.

monosulfide hexafluorine

C.

sulfur hexafluoride

D.

hexasulfur fluoride

The answer to that question is letter A

monosulfur hexafluoride

Explanation:

In the given covalent compound, SF₆, there is one sulfur atom and six fluorine atoms.

The cationic part is sulfur (less electro-negative) and anionic part is fluorine (more electro-negative).

So the more electro-negative fluorine will be named as fluoride and the name of sulfur will be the same : sulfur:

as there are six fluorine so the prefix " hexa"

Hence name will be monosulfur hexafluoride
