In this question, we are given the molecule ab3, and we are told that it can have three different shapes.
00:07
So in the question, we need to sketch and name the three different possible shapes for this molecule.
00:13
And we need to give examples of what that molecule might be.
00:17
So i've put down the vacpr geometry table, you know, that will assist us to identify the shapes.
00:24
So let's begin with writing down, with drawing the different shapes.
00:28
So we're drawing the shapes for a, b3, where a and b are atoms.
00:37
All right, so shape number one, we've got a in the middle, and then we've got b surrounding it.
00:52
So in this case, we have three regions of electron density and zero lone pairs.
00:59
So an example of this would be b, f, so just taking note, we've got three electron pairs and zero loan bonds, the lone pairs, so that's three electron pairs, zero geometry, so that's triconal planner.
01:29
And then the second possible arrangement, a, b, atoms are surrounding the a.
01:50
But in this case, we will have two lone pairs.
01:55
So for this case, we've got one, two, three, four, five regions of electron density.
02:01
So there's five pairs of electrons...
