What purpose does FeCl3 serve in the electrophilic aromatic substitution reaction between chlorine and benzene?
Wiki User

FeCl3 being a Lewis acid accepts one chlorine with electron pair leaving the other as chloronium ion (an electrophile) which attacks on benzene ring.

Why does tetramethyl-lead IV increase the rate of the free radical substitution reaction between methane and chlorine?
Metal ions catalyse the reaction
What type of reaction is Cyclohexene and Bromine?
Electrophilic addition. Forms 1,2,-dibromocyclohexane
What type of reaction between chlorine and butane?
This reaction is of a substitution type by a 'alkyl-radical' mechanism:Cl2 + CH3-CH2-CH2-CH3 --> CH2Cl-CH2-CH2-CH3 + HClor (a bit more in favor)Cl2 + CH3-CH2-CH2-CH3 --> CH3-CHCl-CH2-CH3 + HCl
What is the chemical reaction when acid is added to chlorine?
Reaction between an acid and a metal is usally, salt and hydrogen. So i think the reaction between chlorine and acid forms a salt and a gas.
What is the result of bromine plus chlorine?
no reaction
What happens when benzene is treated with a mixture of concentrated sulphuric acid and nitric acid?
That's an electrophilic aromatic substitution reaction ad will replace a hydrogen with a NO2 group on the ring
Why halobenzenes are less reactive towards nucleophilic substitution reaction?
i think the question is wrong.benzene doesn't respond nucleophilic substitution respond electrophilic substitution it is electrophilic then due to resonance there is a partial double bond between carbon of benzene and halogens.so halobenzenes are chemically inert towards electrophilic substitution.
Why does chlorobenzene give ortho and para products during electrophilic substitution reaction?
As there is an availability of lone pair of electrons on chlorine, it directs the benzene ring towards electrophilic substitution at ortho and para positions.. When we will draw the resonating structures of chloro benzene,we will see that negative charge resides at orho and para positions..
Why electrophilic substitution reaction occur at 2 and 5 position in furan?

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.
Why resorcinol is used as a reagent in test in seliwanoff test?
Resorcinol is used as the complexing agent to provide the color reaction, although the exact nature of the colored product is not known. Since resorcinol favors electrophilic aromatic substitution, the reaction may be similar to the Molisch Test.
What is the mechanism for the reaction between bromine and cyclohexane and state the conditions favor the reaction?
electrophilic substitution. and UV light or heat is required to all the reaction to proceed
Why benzene undergo electrophilic substitution reaction easily and nucleophilic substution reaction with difficulty easily and?
the electron in benzene are delocalised making d ring to be elctron rich,thereby undergoing electrophilic substitution.benzene cannot undergo nucleophillic substitution,it can only undergo if it is substituted with an electron withdrawing group
Definition of electrophilic substitutionat school level?
When a positive ion (electrophile) attacks on a pi bond or partially negative carbon atom and replace H as a positive ion then it is electrophilic substitution reaction.
Why is ICl used in the electrophilic aromatic iodination reaction rather than I 2?
Due to electronegativity difference between Iodine and chloride (chlorine is more electronegative), Iodo has delta positive charge and thus electrophilic reagent. I2 also form hypervalent I with delta positive charge, but ICl is compartively better in generating I with delta positive charge.
What is nucleophilic substitution reaction?
A nucleophile attacks an electrophilic site and replaces a leaving group. e.g. OH- attacks R-Br to give R-OH.
What is electrophilic addition reaction?
The Electrophilic Addition Reaction is when the attacking species during the addition reaction is"Electrophile", it is called "electrophilic addition reaction". Examine: (+) (-) (+) (-) (+) (-) CH2Br-CH2BràH2C-CH2+BrBr-àH2C=CH2+Br2-
