All right, so we're asked to predict the molecular geometry of the molecule brf.
00:07
So we need to know the lewis structure.
00:09
And even if you've never seen this molecule before, you might have seen halogens tend to form diatomic molecules.
00:14
So like br2, f2, and so on.
00:19
And they generally look like if a halogen is represented by x, where x could be br or f, x single bonded to another molecule and then three lone pairs.
00:29
Because when you consider a halogen, it has seven valence.
00:32
And they're all chemically similar because they're in the same group.
00:35
Seven valence electrons means that you want one more, so you want to form one bond, one single bond.
00:41
That's typically the bonding pattern...
