Aromatic chemistry. The very name suggests something sweet and pleasant smelling. I still recall the distinct aromas of purified benzene, toluene, xylene(s), anisole, phenol, benzaldehyde, benzylchloride, aniline, styrene, and naphthalene. It's been over a decade since I whiffed any of those but I'm certain I could score 100% on a blindfolded aroma test for all of them.
Those names are fascinating--despite the stylized suffixes "ene" and "ol". Many are old words derived from older languages like Greek, Persian, Arabic and those of other ancient trading cultures. The root words were probably once familiar to everyday people in those cultures, much like the ancient substance called myrrh. If there were an aromatic hydrocarbon derived from myrrh, I'm certain that chemists would have called it myrrhene.
Few of the aromatics smell bad. But then again, I've always thought the smell of gasoline was rather pleasant. But some of them smell better than others, especially benzaldehyde (which smells like almond extract) and anisole (which smells like licorice). Not so with the saturated straight-chain hydrocarbons: methane, ethane, propane, butane, pentane, hexane, etc. The odors of those are much fainter.
Aromaticity has a whole nother meaning in chemistry, but that will have to wait for another time.
