So here we're looking at a single sela sel gastric, which is also just called aspirin.
00:08
We're looking at how many pie bonds that might signal bones.
00:10
They are.
00:11
And then we're expected.
00:12
Tio.
00:12
No, a little bit about free rotation.
00:15
You'll handle it.
00:15
The end.
00:16
So the pylons are the easiest part.
00:18
You just have to count all the double bonds wants that.
00:22
One, two three, four five for a signal bonds.
00:29
It's a little bit more difficult.
00:30
Weeks count all the single bonds once all the double bonds only count for one, they don't count double.
00:36
That's because a double bonds, one signal and what pie bond and also some of the bonds the hydrogen art show.
00:42
So anytime you see a hydrogen, you know it's a signal bonds.
00:45
They can only form one bonds what has to be sigma.
00:49
So any time you see hye jin, you can also just add a signal bon...
