Determining which molecules are aromatic.
00:04
So we need to follow the rules for aromaticity.
00:07
So we need a molecule to be cyclic.
00:09
We need every atom in the ring to be conjugated.
00:12
Molecules need four n plus 2 pi electrons.
00:15
The molecule must be flat.
00:18
So for example, our first molecule, ch2 positive, this is aromatic, because we fulfill those rules.
00:35
We have another aromatic.
00:44
Next structure we have the incorporation of a heteroatum.
00:49
We've got a nitrogen at the bottom.
00:53
However, this is anti -aromatic, but just non -aromatic.
01:05
Another example, this is non -aromatic.
01:26
Another example, i'm going in order on the list...
