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 center?
It's an area of low electron density, and can be caused, for example, by an incomplete octet. Areas of high electron density are called nucleophilic centres.
Does methanol react with sulphuric acid?
Alcohols can be protonated by strong acids such as sulfuric acid. This is the reaction scheme (I'm simply representing sulfuric acid as a proton source). CH3OH + H+ ---> CH3OH2+ This protonated methanol species, the methyl oxonium ion, is now a pretty decent electrophile and can undergo a nucleophilic substitution.
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.
Is NH3 electrophilic?
No it is not electrophilic.It is a nucleophile
What is different between electrophilic and nucleophilic substation?
Electrophilic reagents are chemical species which in the course of chemical reactions, acquire electrons or a share in electrons from other molecules or ions. Nucleophilic reagents do the opposite of electrophilic reagents.
Why is benzene undergoes electrophilic reaction rather then nucleophilic reaction?

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.
How do you write the nucleophilic substitution reactions for aniline and toluene?
aniline would go through an electrophilic substitution, it is a weak base
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.
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
What is electrophilic center?
It's an area of low electron density, and can be caused, for example, by an incomplete octet. Areas of high electron density are called nucleophilic centres.
Are sigma bonds more electrophilic than pi bonds?
Sigma and pi bonds are nucleophiles. Pi bonds are more nucleophilic than sigma. Electrphilic is not a term usually associated with either sigma or pi bonds.
Comment Pyridine undergo nucleophilic and electrophilic substitution reaction?
Pyridine will add to carbon 3 in electrophilic reactions, such as Bromine addition. However in a nucleophilic reaction, such as seen in the Chichibabin reaction, carbon #2 and #4 are substituted such as if NH2 - attacked. Draw out the resonance forms and you will see this, or consult any Organic text under heterocyclic Chemistry.In a C3 attack, the electrophile will destabilize the C2 and C4 position, to a great extent since N lacks an octet in one of these resonance forms.In a nucleophilic addition, addition at C2 or C4 allows the negative charge to be shared by Nitrogen thus is preferred to the C3 attack.

What type of reaction is exhibited by alkenes?
Alkynes undergo many addition reactions such as: catalytic hydrogenation, addition by electrophilic reagents, hydration with tautomerism, hydroboration reactions, and oxidations. They also undergo nucleophilic addition reactions & reduction. Finally alkynes are the strongest bronsted acids made from only hydrocarbons.
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-
