Pyrrole

Pyrrole is a five-membered aromatic heterocyclic compound with the formula C₄H₅N. It is a colorless liquid with a nutty odor that tends to darken when exposed to air. Unlike pyridine, the lone pair of electrons on the nitrogen atom in pyrrole is part of the aromatic system, making it electron-rich and a very weak base. The pyrrole ring is a vital structural component of many critically important biological molecules. Four pyrrole units are joined together to form the larger porphyrin ring, which is the core of heme in hemoglobin (transporting oxygen in blood) and chlorophyll in plants (enabling photosynthesis).

It will make the broken part even stronger.I decided to go with the ball-and-stick type, as it is easiest to color, is rigid, and looks awesome.The model represents the major resonance contributor.I oriented the mo
