Isomers of … WebAlso, as noted earlier, toluene undergoes nitration about 25 times faster than benzene, but chlorination of toluene is over 500 times faster than that of benzene. From this we may conclude that the nitration reagent is more reactive and less selective than the halogenation reagents. Both sulfonation and nitration yield water as a by-product. electors meeting

WebJan 23, 2024 · Benzene is treated with a mixture of concentrated nitric acid and concentrated sulfuric acid at a temperature not exceeding 50°C. The mixture is held at this temperature for about half an hour. Yellow oily nitrobenzene is formed. You could write this in a more condensed form as: (1) C 6 H 6 + H N O 3 → C 6 H 5 N O 2 + H 2 O WebStep 1: Nitric acid accepts a proton from sulphuric acid and then dissociates to form nitronium ion. Step 2: The nitronium ion acts as an electrophile in the process which further reacts with benzene to form an arenium ion. Step 3: The arenium ion then loses its proton to Lewis base forming nitrobenzene. Sulfonation of Benzene

WebAboutTranscript. The bromination of benzene is an example of an electrophilic aromatic substitution reaction. In this reaction, the electrophile (bromine) forms a sigma bond to the benzene ring, yielding an intermediate. Then, a proton is removed from the intermediate to form a substituted benzene ring. Created by Sal Khan. WebIn the presence of anhydrous Lewis acid (e.g. FeCls or FeBrs), benzene reacts readily with halogens (bromine or chlorine) to produce halobenzenes (bromobenzene or …
