P74 alone: irritable arguments at first, later a good day with my girlfriend

Tacitus supposedly said 74 was between ANOL and EST, roughly. Now, the structure of EST and ANOL is quite alike. It’s just that the first ring has some double bonds. http://upload.wikimedia.org/wikipedia/commons/0/0c/Estratetraenol_chemical_structure.png

Tacitus:

Alpha NOL has a left and right isomer. BNOL, I don’t know. EST could have a Alpha and Beta form or isomers of either. I really don’t know. That’s what he was getting at. I can’t remember IUPAC naming without a Dummies book.

Compare ANOL, in my avatar. I don’t know what EST smells like.
