A derivative of this molecule is the one most commonly phosgenated to form its diisocyanate (“die-eye-so-cyan-ate”), which then reacts with polyols (“polly-alls”) to form polyurethane. A derivative of this organic molecule formed as a byproduct of saccharin synthesis is often used as a strong acid in the acetalization of aldehydes. This molecule reacts with chromyl chloride via an ene (“een”) reaction, then undergoes a [2,3]-sigmatropic rearrangement to form an aldehyde in the classical formulation of the (*) Étard reaction. This molecule appears second in the initialism of a mixture used to produce petrochemicals like polystyrene. Sulfonyl chloride para-substitutes this molecule to form a molecule that reacts with alkyl alcohols to form sulfonate esters also called tosylates. This molecule is nitrated three times to form TNT. For 10 points, name this monomethylated derivative of benzene. ■END■
ANSWER: toluene [or methylbenzene] (The mixture is the BTX mixture.)
