What happens when nitrobenzene reacts with bromine?

Nitrobenzene reacts with Br2 in the presence of FeBr3 to give m-bromonitrobenzene as the major product.

What is bromination reaction?

Bromination: Any reaction or process in which bromine (and no other elements) are introduced into a molecule. Bromination of an alkene by electrophilic addition of Br2. Bromination of a benzene ring by electrophilic aromatic substitution.

What type of reaction is bromination?

The bromination of benzene is an example of an electrophilic aromatic substitution reaction. In this reaction, the electrophile (bromine) forms a sigma bond to the benzene ring, yielding an intermediate.

What is the product of the reaction of the benzene with bromine?

The reaction between benzene and bromine in the presence of either aluminum bromide or iron gives bromobenzene.

What would be the major product of the reaction between nitrobenzene and Br2 FeBr3?

When nitrobenzene is treated with Br2 in the presence of FeBr3, the major product formed is m- bromonitrobenzene.

What is the product formed when nitrobenzene reacts with bromine in the presence of iron bromide?

When nitrobenzene is treated with Br2​ in the presence of FeBr3​, the major product formed is m-bromonitrobenzene.

What is the major product of bromination of propane?

As a simple example, consider the following transformations of the simple alkane propane. Bromination, by the action of bromine together with heat or light energy, produces a mixture of 1-bromopropane and 2-bromopropane. We recognize this as a substitution reaction (a bromine atom replaces a hydrogen).

Which is the correct product formed from the bromination of nitrobenzene?

Bromination of nitrobenzene requires strong heating and produces the meta-bromo isomer as the chief product.

What happens when methane reacts with bromine?

When a mixture of methane and bromine is exposed to ultraviolet light – typically sunlight – a substitution reaction occurs and the organic product is bromomethane. That means that you could get any of bromomethane, dibromomethane, tribromomethane or tetrabromomethane.

Why does nitrobenzene not give Friedel Craft reactions?

Nitrobenzene does not undergo Friedel-Crafts reaction, because the nitro group in nitrobenzene is a strong withdrawal group and this group repels the electrophile from it. Hence, nitrobenzene will not undergo Friedel-Crafts reaction easily.

What are the products of bromination?

In the addition of bromine to cyclohexene, for example, cis and trans-1,2-dibromocyclohexane are both possible products of the addition. Since the trans-isomer is the only isolated product, this reaction is stereoselective.

What is the major product of bromination of A?

But bromine is highly regioselective in where it attacks. The relative rates of attack at the different types of H atom are 3°:2°:1° = 1640:82:1. So the major product is C, 2-bromo-2-methylbutane.

What is the product isomer of nitrobenzene after bromination?

Bromination of nitrobenzene requires strong heating and produces the meta-bromo isomer as the chief product. Some additional examples of product isomer distribution in other electrophilic substitutions are given in the table below.

What happens when nitrobenzene reacts with deactivating groups?

Bromination of nitrobenzene: Deactivating groups form electrophilic substitution more hard but the reaction will carry on within more forcing reaction conditions. Though, substitution is now directed to the meta position. This can be described through comparing all the possible resonance structures taking place from ortho, Meta and para attack.

What is the catalyzed reaction of ethyl benzene with bromine?

catalyzed reaction of ethyl benzene with bromine gives the following ratio of products. The ortho and para isomers are the two major ones, whereas the meta isomer is only present in a small amount.

What is the reaction between benzene and nitric acid?

Ch17 Reactions of Aromatic Compounds (landscape).docx Page7 Nitration of Benzene Benzene will react with hot concentrated nitric acid to produce nitrobenzene. However, this reaction proceeds slowly, which is inconvenient (dangerous) since hot, conc. nitric acid is a powerful oxidizer, and organic compounds are easily oxidizable.
