electrophilic substitution in methylbenzene and nitrobenzene

WebBenzene’s ring of delocalisation is very strong, meaning it doesn’t take part in addition reactions. Most of the reactions of benzene are instead electrophilic substitution reactions. Electrophilic substitution reactions of benzene include: Nitration, producing nitrobenzene. Chlorination, producing chlorobenzene. WebNO_2 group is a deactivating and meta - directing group for electrophilic substitution reactions. It is due to the electron withdrawing tendency of NO_2 group. Thus, … WebCompare the stability of the sigma complexes for the ortho-bromination of nitrobenzene and the meta-bromination of benzaldehyde. Show transcribed image text. Expert Answer.

"WebThe mechanism for nitration of benzene: Step 1: Nitric acid accepts a proton from sulphuric acid and then dissociates to form nitronium ion. Step 2: The nitronium ion acts as an electrophile in the process which further reacts with benzene to form an arenium ion. Step 3: The arenium ion then loses its proton to Lewis base forming nitrobenzene. " - Halogenation of nitrobenzene

WebJan 5, 2024 · So, chlorination of nitrobenzene gives m-chloronitrobenzene. b. Chloro group is ortho and para directing group. So, sulphonation of chlorobenzene gives p-chlorobenzene sulphonic acid and o-chlorobenzene sulphonic acid. c. Phenolic -OH group is ortho and para directing group. So, bromination of phenol gives p- bromophenol and o-bromophenol. d. WebFeb 1, 2024 · Nitrobenzene is a compound derived from benzene and quite fundamental in the petrochemical industry. One of which is in the manufacture of aniline. Aniline has an important role as dyes, synthetic rubber materials, rocket fuels and pharmaceuticals. Nitrobenzene can be synthesized by the nitration reaction of benzene.

WebBromination of methoxybenzene (anisole) is very fast and gives mainly the para-bromo isomer, accompanied by 10% of the ortho-isomer and only a trace of the meta-isomer. Bromination of nitrobenzene requires strong heating and produces the meta-bromo isomer as the chief product. WebThe facts. Benzene reacts with chlorine or bromine in an electrophilic substitution reaction, but only in the presence of a catalyst. The catalyst is either aluminium chloride (or aluminium bromide if you are reacting benzene with bromine) or iron. Strictly speaking iron isn't a catalyst, because it gets permanently changed during the reaction.
