WebMar 8, 2024 · In organic chemistry, aromatic hydroxy compounds in which one or more hydroxyl groups are directly attached to the aromatic nucleus (i.e. benzene like a ring) are called phenols. The class name ‘phenols’ is adopted from the simplest member, monohydric benzene (in Greek Phene means benzene, ol means OH). WebJul 31, 2024 · This ion is formed from nitric acid and sulfuric acid according to the following equation: HNO 3 + 2H 2SO 4 ⇌ NO + 2 + H 3O + + 2HSO − 4 The nitronium ion attacks the aromatic ring to give first a nitrobenzenium ion and then an aromatic nitro compound: movie theater in mooresville https://zambezihunters.com

The more electron-rich the aromatic ring, the faster the reaction Groups that can donate electron density to … WebThis is often called a +R (for resonance) effect, and this activates the ring towards EAS. Other groups contain an electronegative atom attached via a π-bond (e.g., C=O) that makes the group electron-withdrawing. These groups act as π-acceptors, drawing electron density away from the ring via resonance. movie theater in monticello indiana

The objectives were to … Both the regioselectivity—the diverse arene substitution patterns—and the speed of an electrophilic aromatic substitution are affected by the substituents already attached to the benzene ring. In terms of regioselectivity, some groups promote substitution at the ortho or para positions, whereas other groups favor substitution at the meta position. These groups are called either ortho–para directing or m…
