Hello.
00:04
In this problem, we're looking at the cause of the smell of skunks that we all hate so much.
00:11
And this actually follows after the previous problem in this same textbook, problem number 116, that used the same compound to explain why people cry when you cut raw onions.
00:24
Now, i was not aware that the same compound caused the smell of onions as they do causes smell of skunks, which does, quite frankly, explain a lot why i hate it.
00:32
Onion so much.
00:34
But moving on.
00:35
In the previous problem, we found one of the forms that this compound takes.
00:40
And so this is a little bit of a giveaway.
00:42
You can watch the previous video to see.
00:44
We learned in the last problem that one of the formats, or one of the ways that this molecule can be drawn, looks something like this.
01:00
And then we've got hydrogens, just like this.
01:09
All right.
01:10
We were given a little bit more information in the previous problem.
01:13
In fact, they gave us the name of the compound, which helped us piece together how everything was connected.
01:19
Now, in this problem, they don't give us the name.
01:20
They're just asking for a generic, what could be another isomer? and an isomer just means what's another way we could have drawn this molecule, had all the electrons still in it, and had created something.
01:31
Well, there's a few different things you could do, right? to rearrange this, one of those ways could simply to split up or switch, say, the oxygen with one of the hydrogens.
01:45
And quite frankly, it could be any hydrogen.
01:47
You could pick any hydrogen on this whole compound and just swap things out.
01:51
Right.
01:52
So let's say that instead of this one, let's say we will put the oxygen here.
02:02
Everything else will leave the same, but now that hydrogen needs to go somewhere.
02:10
Let's put this over here and this here.
02:14
And let's just see if we can get this to be a reasonable compound.
02:18
Adding up the valence electrons here, i've got the periodic table off to the side that has your valence electrons written in.
02:24
We'll need our valence to know if we need to do double bonds or how many loan pairs we've got.
02:29
So this compound has, first off, we've got three carbons.
02:33
Carbons have four electrons each, so four times three, plus six hydrogens.
02:39
Each one of those has one, so one times six, and oxygen has six valence, and a sulfur also has six, for a grand total of 30 valence electrons.
02:53
So 30 electrons going in our structure.
02:57
Now so far, how many bonds do we have? one, two, three, four, five, six, seven, eight, nine, ten bonds so far.
03:04
So if there's two electrons per bond, that's 20 electrons used up so far...
