Why does nitrobenzene give meta product?
Nitro group is an electron withdrawing group. Therefore, it is a meta directing group. Hence the attachment of a new nitro group occurs in the meta position. Hence the product will be meta-dinitrobenzene.
What is the product of nitration?
The common explosive TNT (trinitrotoluene) is actually a product of nitration. TNT is made by taking toluene and nitrating it three times. Another important use for aromatic nitro compounds is as azo-dyes.
How is nitrobenzene prepared in laboratory?
Production. Nitrobenzene is prepared by nitration of benzene with a mixture of concentrated sulfuric acid, water, and nitric acid. This mixture is sometimes called “mixed acid.”
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 happens when nitrobenzene reacts with bromine?
Nitrobenzene reacts with Br2 in the presence of FeBr3 to give m-bromonitrobenzene as major project.
What is the final product of nitration?
Hence, toluene undergoes nitration to give ortho and para nitro toluene isomers, but when heated it can give dinitrotoluene and ultimately the explosive trinitrotoluene.
What is the product of nitration of methyl benzoate?
Nitration is the substitution of an NO2 group for one of the hydrogen atoms on a benzene ring. In this experiment the students nitrate methyl benzoate. The reaction is regioselective and produces predominantly methyl 3-nitrobenzoate.
Which product is major ortho or para?
When electrophilic substitution reaction takes place, and the ortho and para products are formed then among them para is considered as the major product and ortho as a minor product. The reason behind this is the steric hindrance.
