In case of nitration of benzene
WebThe mechanism of nitration of benzene involves three steps which are given below. STEP 1: Formation of nitronium ion (NO2+) from Nitric acid The nitronium ion is formed by the reaction of nitric acid with sulfuric acid. Sulfuric acid will protonate nitric acid leading to a loss of water moleculeand formation of nitronium ion. WebNitration of benzene is the name for such a process. The mechanism of benzene nitration is as follows: Step 1: Nitric acid absorbs a proton from sulphuric acid before dissociating to generate the nitronium ion. Step 2: In the reaction, the nitronium ion functions like an electrophile, reacting with benzene to generate an arenium ion. Step 3 ...

WebThe mechanism of sulfonation is similar to nitration, but the electrophile in this case is the sulfur trioxide(SO3) molecule, which is generated in situ from the reaction between sulfuric acid and an oxidizing agent. ... The overall r eaction for the nitration of benzene is: C6H6 + HN O3 → C 6H 5NO2 + H2O. Examples of nitro aromatic compounds ... WebIf we use the nitration of benzene as a reference, we can assign the rate of reaction at one of the carbons to be 1.0. Since there are six equivalent carbons in benzene, the total rate would be 6.0.
WebWhen a monosubstituted benzene undergoes an electrophilic aromatic substitution reaction, three possible disubstitution products might be obtained. For example, nitration of bromoben-zene could in principle give ortho-,meta-, or para-bromonitrobenzene. If substitution were totally random, an ortho:meta:para product ratio of 2:2:1 would be ... WebTherefore, in the case of the halobenzenes these two effects are working in opposite directions. In order to determine which effect controls the reaction, we need some data . The following table compares the relative rates of electrophilic aromatic nitration of the halobenzenes to the rate for benzene itself.
