Task: Text Categorization
Input (English): This molecule has uniform bond lengths of 140 picometers. A strong Lewis acid catalyst can be used to alkylate or acylate this molecule. Alternating carbon-carbon single and double bonds characterize this molecule's two resonance structures, which represent its six delocalized pi electrons. Huckel's rule describes this molecule's structure, which was first discovered by August Kekul. Adding an -OH group to this molecule produces phenol, while adding a CH3 group to it makes toluene. For 10 points, name this aromatic compound with formula C6H6.
Output (English): Science
