In this problem, we're given lewis structures, and we're asked about the electron domain geometry and the molecular geometry.
00:09
So for electron domain, it means that our extra electron pairs on our central atom, we treat that as if it's another bond.
00:20
So that means here, you treat it kind of like this.
00:24
So that would be three connections to our central atom.
00:28
So that would be trigonal planar, but the molecular geometry, we then differentiate between bond pairs and moment pairs.
00:41
So this would be bent.
00:46
So then if we look at our next one, we have two pairs of electrons here.
00:51
So if we act like those are bond pairs, we'd have four connections to our central atom.
00:56
So here we'd have a tetrahedral for our electron pair geometry.
01:02
But when we treat those differently from our bond pairs, we get bent geometry for our molecular geometry.
01:10
Our next one here, we have no extra electrons on our central atom...
