WARNING: The structure is very wrong. What should be an ethylamine chain at position 3 is actually a propylamine chain at P2. Next, there should not be a double bond between P1-P2, as there would be major problems with its interaction with the necessary P2-P3 double bond: Steric hindrance, electron repulsion, and the bond angle (which would be linear, and if it were even possible, it would also prevent the bond angles needed for the pyrrole). This next part is not a problem when the chain is moved, but as it sits, the P2 carbon is also breaking the octet rule; P1 would need to have a positive charge, and P2 a negative charge. But this is so wrong (because Carbon never has 5 bonds), so it's almost not even worth mentioning. I only mention it because I want to emphasize how bad Al is with chemical structures (currently). Even the bond angles for the dimethylamine are wrong, but this is a small error, as they are technically occupied and potential bond angles, but are a minority in the molecule's natural vibrations, as the angle shown is far less stable than the traditional depicted angle. I love Al, but it's terrible with chemical structures. I have been unable to find any AI that can accurately draw higher-order structures (yet!).
