Okay, we are asked to draw the lewis structures and then tell the molecular shape for, i believe we have 1, 2, 3, 4, 6 species.
00:13
Let's begin.
00:14
Our first one is germanium tetra bromide, g -e -v -r -4, and i'm pulling a periodic table here so i can see where i am.
00:35
And let's see.
00:38
I believe this is going to be, where's my periodic table? there it is.
00:43
Yep, germanium is right under carbon.
00:47
So this will be tetrahedral.
00:48
And let me get a black pen here.
01:08
And then i'm going to go a little bit darker for my dots.
01:20
Okay, now let's go back to this.
01:23
What is next? pf5.
01:29
I believe that this is going to be, guessing it's p, i'm guessing it's trigonobipyramidil.
01:44
And that'll be p.
01:48
That'll be bipramidal, one, two.
02:14
And again, this is trigonal.
02:20
Bi -pir -middle.
02:26
Okay, let's move down a bit and see what my next one is.
02:32
I -c -3, and then we'll have c -h -2 -o.
02:43
I -c -3.
02:45
That one, i'm guessing i, and i'm guessing it's going to have two and shared.
03:00
I'm going to have, i'm going to have one up and one down.
03:21
I'm going to have two unshared pairs of electrons.
03:26
I'm going to do this as two across.
03:33
It doesn't really matter where i put them, i guess.
03:35
So there's my shape of this one.
03:43
This is going to be t -shaped for my molecular structure, and it's got trigonoberemitral electron geometry.
03:59
What did i say was next? c -h -2 -o.
04:09
And that will be c .h2o.
04:20
I'll have c.
04:25
I think it's going to be trigonal planar...
