In this problem, we're looking at co -02, and we're told chlorine will have an expanded octet.
00:06
So we want to draw our loose structure to answer questions about this.
00:13
So first we look at how many electrons we have.
00:16
So for valence electrons, chlorine has seven, and each oxygen has six.
00:27
So that's going to give us 19 electrons.
00:33
Each oxygen will get an octet, so that's 16 electrons.
00:38
So we have a three electron difference that will go on our central atom chlorine, and we want to minimize formal charges.
00:46
So we know we have at least a single bond out to each oxygen, but oxygen, ideally, in order to have a formal charger zero, has two bonds and two lone electron pairs...
