Nitrobenzene is highly toxic (Threshold Limit Value 5 mg/m ) and readily absorbed through the skin. Prolonged exposure may cause serious damage to the central nervous system, impair vision, cause liver or kidney damage, anemia and lung irritation. Inhalation of vapors may induce headache, nausea, fatigue, dizziness, cyanosis, weakness in the arms and legs, and in rare case… WebThe nitration of methylbenzene (toluene) Methylbenzene reacts rather faster than benzene - in nitration, the reaction is about 25 times faster. That means that you would use a lower temperature to prevent more than one nitro group being substituted - in this case, 30°C rather than 50°C. Apart from that, the reaction is just the same - using ...

14.2. Examples of electrophilic aromatic substitution

WebThe lone pair on the nitrogen in the phenylamine picks up a hydrogen ion from the acid. The electron-half-equation for this reaction is: The nitrobenzene has been reduced by gaining electrons in the presence of the acid. The electrons come from the tin, which forms both tin (II) and tin (IV) ions. WebAromatic nitro compounds are typically synthesized by nitration. Nitration is achieved using a mixture of nitric acid and sulfuric acid, which produce the nitronium ion ( NO+ 2 ), which is the electrophile: + H + The nitration product produced …
