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 electrophilic substitution mechanism. Stage one. As the NO 2 + ion approaches the delocalised electrons in the benzene, those electrons are strongly attracted towards the positive charge.. Two electrons from the delocalised system are used to form a new bond with the NO 2 + ion. Because those two electrons aren't a part of the delocalised system …

WebCorrect option is D) The rate of nitration of benzene is equal to the rate of nitration of hexa deutero benzene because the rate determining step does not involve the breaking of C-H … WebWhy chloro benzene undergoes nitration about 30 times slower than benzene? It is less attractive for electrophiles, and so the reaction is slower. Since chlorine is an electron withdrawing group, so it withdraws electron from aromatic ring. As a result of which the electron density of the aromatic ring decreases and deactivates the ring.
