What is the Lewis structure for SF2?

Florine doesn't do double bonds as its a halogen, only needing one more valence electron to enter the noble gas structure (filling its outer shell).

Therefore only answer choice B is an option.

There are a lot of people who use the Lewis structure when they want to show the bonds between the atoms and the molecules. This will also make it evident if there are lone pairs of molecules that can be seen.

Chemists normally use this in order to show possible predictions that may occur when there are different chemicals that are mixed together. It is important to see the number of valence electrons. The Lewis structures of different compounds are different from each other.
