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. WebDec 15, 2024 · The process of nitration is a type of electrophilic substitution reaction. An electrophile is any compound that has the affinity to attract electrons towards itself.
