Why nitration of nitrobenzene is difficult than nitration of benzene?
Nitration of nitrobenzene is more difficult because the nitro group is an electron-withdrawing group, making the nitrobenzene less reactive towards electrophilic aromatic substitution reactions. In contrast, benzene is more reactive because it does not have any electron-withdrawing groups attached to it.
How do you convert benzene to m-bromoaniline?
1. benzene to nitro benzene through nitration 2. nitro benzene to m-bromonitrobenzene by bromination 3. m-bromonitrobenzene to m-bromoaniline through halogenation in presence of Sn+HCl.
Is nitrobenzene polar?
Yes, nitrobenzene is a polar compound due to the electronegative nitro group attached to the benzene ring. This creates an uneven distribution of charge, with the nitro group being more negative and the benzene ring being more positive, resulting in a polar molecule.
What is the colour of nitro-benzene?
Nitrobenzene is a pale yellow to light brown liquid at room temperature.
What is the function of sulphuric acid in the nitration of benzene?
Sulfuric acid acts as a catalyst in the nitration of benzene by protonating the nitric acid, which generates a more reactive electrophile (NO2+). This electrophile then attacks the benzene ring to introduce the nitro group during the nitration process.
What is the different between benzene and nitro benzene?
Benzene is a colorless, aromatic hydrocarbon with a ring structure, while nitrobenzene is a derivative of benzene with a nitro group (-NO2) attached to the ring. Nitrobenzene is a pale yellow liquid with a distinctive odor, and it is often used as a precursor in the synthesis of various chemicals.
How can you rduced nitro benzene into Aniline?
With hydrogen in a catalized reaction
What is the name of Co(H2O)4ClNO2br2?
Tetra aqua chloro nitro cobalt 3 bromide

Is Nitro Benzene CIB registered in Agriculture use?
No. Up to now it is not registered in CIB.
How do you convert benzene to m-bromoaniline?

What is example of nitration reaction?
An example of a nitration reaction is the nitration of benzene to form nitrobenzene. In this reaction, benzene reacts with a mixture of concentrated nitric acid and sulfuric acid, where the sulfuric acid acts as a catalyst. The electrophilic aromatic substitution occurs, resulting in the introduction of a nitro group (–NO₂) onto the benzene ring. This reaction is significant in organic chemistry for synthesizing various nitro compounds.
What is the function of sulphuric acid in the nitration of benzene?
Sulfuric acid acts as a catalyst in the nitration of benzene by protonating the nitric acid, which generates a more reactive electrophile (NO2+). This electrophile then attacks the benzene ring to introduce the nitro group during the nitration process.
Can benzene be replaced by nitrobenzene in friedel crafts alkylation?
The process would be unfavourable since the nitro (-NO2) group is strongly deactivating and would render the benzene ring in nitrobenzene less susceptible to electrophilic attack.
Mechanism for preparation of m-nitro aniline from m-dinitrobenzene?
M-nitroaniline can be prepared from m-dinitrobenzene by reducing one of the nitro groups to an amino group. One common method is to use a reducing agent like tin and hydrochloric acid in a strongly acidic medium, which leads to the conversion of one nitro group to an amino group to yield m-nitroaniline.
