What is product of styrene react with bromine?
When styrene reacts with bromine, it undergoes electrophilic aromatic substitution to form bromostyrene. This reaction involves the addition of a bromine atom to the benzene ring of the styrene molecule.
What happens when bromine reacts with an phenol?
When bromine reacts with phenol, it undergoes electrophilic aromatic substitution to brominate the aromatic ring. The reaction takes place under mild conditions without a catalyst, and the product formed is a bromophenol compound.
What reagent you use to convert aniline into chlorobenzene?
You can convert aniline to chlorobenzene by reacting it with chlorine in the presence of a Lewis acid catalyst such as iron (III) chloride (FeCl3). The reaction proceeds via electrophilic aromatic substitution to replace the amino group with a chlorine atom on the benzene ring to form chlorobenzene.
What is the product of a reaction between bromine and aniline in non polar solvent?
The product of a reaction between bromine and aniline in a non-polar solvent is typically the bromination of aniline, where bromine substitutes a hydrogen atom on the benzene ring of aniline to form bromoaniline. This reaction is an electrophilic aromatic substitution reaction.
How would eugenol react with bromine in carbon tetrachloride?
Eugenol would undergo electrophilic aromatic substitution with bromine in carbon tetrachloride. The bromine would replace a hydrogen atom on the benzene ring of eugenol, resulting in the formation of a brominated eugenol derivative.
How does salicylamide participate in electrophilic aromatic substitution reactions?
Salicylamide participates in electrophilic aromatic substitution reactions by donating electrons to the electrophile, which is a species that seeks electrons. This donation of electrons helps to stabilize the intermediate formed during the reaction, allowing for the substitution of a hydrogen atom on the aromatic ring with the electrophile.
What reaction does aromatics undergo?
Aromatics can undergo electrophilic aromatic substitution reactions, where an electrophile replaces a hydrogen atom on the aromatic ring. This leads to the formation of a new substituted aromatic compound.
What happens when benzene reacts with chlorine in bright sunlight?
When benzene reacts with chlorine in bright sunlight, substitution reactions can occur where one or more hydrogen atoms in the benzene ring are replaced by chlorine atoms, forming chlorobenzene derivatives. This process is known as chlorination and is a type of electrophilic aromatic substitution reaction.
In electrophilic aromatic substitution why do halogen atoms direct ortho para and which halogen is most deactivating?
Halogens have lone pairs which they can donate into the aromatic pi system (easy to see with resonance structures), hence they are ortho/para directors. However, they deactivate the ring to electrophilic reaction because they are electronegative. Therefore fluorine is the most deactivating since it is the most electronegative.
How does the reaction of phenol with Br2 proceed?
The reaction of phenol with Br2 proceeds through electrophilic aromatic substitution, where the bromine atom replaces a hydrogen atom on the benzene ring of phenol. This reaction is facilitated by the presence of the hydroxyl group on the phenol molecule, which activates the benzene ring towards electrophilic attack.
Do ester react with bromine?
Yes, esters can react with bromine in the presence of a Lewis acid catalyst to undergo electrophilic aromatic substitution, resulting in the addition of bromine atoms to the ester molecule. This reaction is known as the Hunsdiecker reaction.
Which observations are made in the reaction of toulene with bromine water?
When toluene reacts with bromine water, it undergoes electrophilic aromatic substitution. The color of the bromine water fades from orange to colorless due to the addition of bromine to the aromatic ring of toluene, forming bromotoluene. This reaction is used to test for the presence of aromatic compounds.
Why is anisole ortho and para director towards electrophile substitution reaction?
Anisole is ortho and para directing in electrophilic aromatic substitution reactions because the lone pairs on the oxygen atom can donate electron density to the ring through resonance, stabilizing the carbocation intermediate formed during the reaction at the ortho and para positions. This makes those positions more favorable for electrophilic attack.
What is the major product of reaction of 4-Ethyl methoxy benzene in the presence of chlorine and AlCl3?
The major product would be the chlorination of the 4-ethyl group, forming 4-chloroethyl methoxy benzene. The AlCl3 acts as a Lewis acid catalyst to facilitate the electrophilic aromatic substitution reaction.
Why electrophilic substitution reaction occur at 2 and 5 position in furan?

How does the methyl group directing effect influence the reactivity and regioselectivity of electrophilic aromatic substitution reactions?
The methyl group directing effect increases the reactivity of electrophilic aromatic substitution reactions by directing the incoming electrophile to the ortho and para positions on the benzene ring. This effect is due to the electron-donating nature of the methyl group, which stabilizes the positive charge on the intermediate carbocation. As a result, the regioselectivity of the reaction is influenced, favoring the formation of ortho and para substituted products.
Why the electrophilic substitution going to occur in furon thiophene and pyrole?
Electrophilic substitution occurs in furan, thiophene, and pyrrole because these compounds have a lone pair of electrons on the heteroatom (oxygen, sulfur, or nitrogen), making them nucleophilic and reactive towards electrophiles. The aromaticity of these compounds is also maintained during the substitution reaction, making them favorable candidates for electrophilic substitution.
