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. 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.
