What is electrophilic substitution reaction of benzene?
Electrophilic substitution of benzene is the one where an electrophile substitutes the hydrogen atom of benzene. As the aromaticity of benzene is not disturbed in the reaction, these reactions are highly spontaneous in nature.
What is monosubstituted benzene?
Monosubstituted Benzene When one of the positions on the ring has been substituted with another atom or group of atoms, the compound is a monosubstituted benzene. If two positions are replaced, then it’s a disubstituted, & so on.
What are ortho positions of monosubstituted benzene ring?
They are defined as the following: ortho- (o-): 1,2- (next to each other in a benzene ring) meta- (m): 1,3- (separated by one carbon in a benzene ring) para- (p): 1,4- (across from each other in a benzene ring)
Which substituent is least deactivating?
The ring that is substituted with the most electronegative halogen is the most reactive ring ( less deactivating substituent ) and the ring that is substituted with the least electronegatvie halogen is the least reactive ring ( more deactivating substituent ), when we compare rings with halogen substituents.
What is an example of electrophilic substitution?
This reaction is known as electrophilic substitution. Examples of electrophilic species are the hydronium ion (H3O+), the hydrogen halides (HCl, HBr, HI), the nitronium ion (NO2+), and sulfur trioxide (SO3).
What is the difference between monosubstituted and disubstituted?
The key difference between monosubstituted and disubstituted alkene is that a monosubstituted alkene compound has a covalent bond with only one carbon, excluding the doubly bonded carbon atoms of the alkene, whereas disubstituted alkene compound has two carbon atoms bonded to the double-bonded carbon atoms of the …
How many product of monosubstituted benzene are possible?
Since a mono-substituted benzene ring has two equivalent ortho-sites, two equivalent meta-sites and a unique para-site, three possible constitutional isomers may be formed in such a substitution.
How many isomers are possible for Monosubstituted and di substituted benzene?
There is one mono substituted benzene and three di substituted benzene i.e. ortho, para and meta.
What is electrophilic substitution reaction give an example?
Examples of the Electrophilic Substitution Reaction The formation of bromobenzene due to the bromination of benzene is an example of an electrophilic aromatic substitution reaction. Also, the chlorination of the acetone is an example of an electrophilic aliphatic compound.
What is electrophilic substitution reaction explain with 3 example?
Nitration and sulfonation of benzene are two examples of electrophilic aromatic substitution. The nitronium ion (NO2+) and sulfur trioxide (SO3) are the electrophiles and individually react with benzene to give nitrobenzene and benzenesulfonic acid respectively.
