WebWhen benzene undergoes electrophilic substitution, the product retains the stability associated with an aromatic system. This stability is lost in electrophilic addition because the product is not aromatic. In the bromination of benzene using Br2 and FeBr3, is the intermediate carbocation aromatic? Explain. WebAug 7, 2024 · As far as I know, many electrophilic aromatic substitution reactions fail to undergo the usual way in aniline. This is due to $\ce{-H2N}$ group being basic (pKa of …
WebNov 14, 2024 · Phenol undergoes electrophilic substitution reaction more readily than benzene. Using the same reaction condition when benzene gives mono-substituted product, phenol gives tri-substituted phenol. By improving the condition it is possible to form mono or di substituted phenol. Nitration of phenol Phenols are o , p – directory. WebAnswer (1 of 2): In acidic medium phenol will undergo electrophilic substitution much faster than aniline. Both aniline and phenol undergo electrophilic substitution more easily than benzene in neutral conditions because of the +M effect of the NH2 and OH groups that activate the benzene ring at...
