Why does chlorobenzene give ortho and para products during electrophilic substitution reaction?
Rashitabhuju
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..

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
What are the products of a toluene-sulfuric acid reaction?
toulene+sulphuric acid = o-methyl benzene sulphonic acid + p-methyl benzene sulphonic acid. Since methly group is ortho and para directed group so it activates benzene ring for electrophilic substitution reaction.
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 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 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.
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 electrophilic substitution reaction occur at 2 and 5 position in furan?

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.
What are the products of a toluene-sulfuric acid reaction?
toulene+sulphuric acid = o-methyl benzene sulphonic acid + p-methyl benzene sulphonic acid. Since methly group is ortho and para directed group so it activates benzene ring for electrophilic substitution reaction.
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-

That's an electrophilic aromatic substitution reaction ad will replace a hydrogen with a NO2 group on the ring
Why is benzene undergoes electrophilic reaction rather then nucleophilic reaction?

What is Reaction of triethyl phosphite with aidehyde?
phophite attacks the electrophilic carbon, the oxyanion attacks the another electrophilic carbon and its anion will be cyclised with phosponiumion.
