Heterocycles Part 1: Furan, Thiophene, and Pyrrole

We've mentioned heterocycles before. They are cyclic molecules where one or more atoms in the ring are not carbon. Typically these involve oxygen, nitrogen, and sulfur. But there are so many different heterocycles. Different sizes, some aromatic and some not, and many of them are important for synthesis. Let's look at a few key heterocycles now, those being furan, thiophene, and pyrrole.

    I spent almost my whole night searching for explanation of the order of aromaticity of these prominent heterocycles. I am glad I have come to my bus-stop. I have learnt that the order depends on the resonance stabilization energy. Benzene>Thiophene>pyrrole>Furan.

    I can't get over how you decided to upload this at the time right after I attended the lecture for diels-alder reactions & aromacitiy. It's like you know somehow that 2nd semester Orgo students are being taught aromatics at this exact moment.

    Wasn‘t there somethinh with the protonation of pyrrole? We were taught that the protonation also occurs on the C3. But one of the protonation reaction can undergo a ring opening reaction. Idk, I haven‘t really understood it, so that‘s why I‘m here.
