Difference Between Electrophilic and Nucleophilic Aromatic Substitution

The main difference between electrophilic and nucleophilic aromatic substitution is that electrophilic aromatic substitution involves the replacement of an atom of the aromatic compound with an electrophile whereas nucleophilic aromatic substitution involves the replacement of an atom of the aromatic compound with a ...

What is the difference between electrophilic and nucleophilic?

The main difference between electrophile and nucleophile is that electrophiles are atoms or molecules that can accept electron pairs whereas nucleophiles are atoms or molecules that can donate electron pairs.

What is the difference between electrophilic substitution and electrophilic addition?

When an electrophile replace an atom from an compound the reaction is called electrophilic substitution reaction. while when an electrophile directly add to the compound the reaction is called electrophilic addition .

What is nucleophilic aromatic substitution reaction?

From Wikipedia, the free encyclopedia. A nucleophilic aromatic substitution is a substitution reaction in organic chemistry in which the nucleophile displaces a good leaving group, such as a halide, on an aromatic ring.

What is electrophilic substitution reaction give examples?

Nitration and Sulfonation. 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.

IS NO+ an electrophile?

The nitrogen in NO2+ does not have an octet around it, hence it is an electrophile.

Is Roh an electrophile?

When R-O-H is an electrophile, the R-O bond is broken. C. When R-O-H is an electrophile, the OH should be pronated because OH is a poor leaving group.

What is the electrophile in electrophilic addition?

Electrophilic addition is a reaction between an electrophile and nucleophile, adding to double or triple bonds. An electrophile is defined by a molecule with a tendency to react with other molecules containing a donatable pair of electrons.

How does nucleophilic substitution work?

In all of these nucleophilic substitution reactions, the carbon-halogen bond has to be broken at some point during the reaction. The harder it is to break, the slower the reaction will be. ... In the other halogenoalkanes, the bonds get weaker as you go from chlorine to bromine to iodine.

What is nucleophilic substitution reaction give an example?

An example of nucleophilic substitution is the hydrolysis of an alkyl bromide, R-Br under basic conditions, where the attacking nucleophile is OH⁻ and the leaving group is Br⁻. Nucleophilic substitution reactions are common in organic chemistry. Nucleophiles often attack a saturated aliphatic carbon.

What is electrophilic aromatic substitution used for?

Electrophilic aromatic substitution is one of the most important reactions in synthetic organic chemistry. Such reactions are used for the synthesis of important intermediates that can be used as precursors for the production of pharmaceutical , agrochemical and industrial products.

What conditions are needed for nucleophilic substitution?

1 Answer

• 1.) Solvent. SN2 - polar Aprotic ( no O-H or N-H bonds) ...
• 2.) Substrate ( Leaving group (LG) attached to the carbon is...) SN2 - methyl > primary > secondary (you want the LG to be less crowded)
• Side Note : SN2 - Watch out of the steric hindrance blocking the nucleophile. SN1 - Stabilizing the carbocation formed.

What is the purpose of electrophilic aromatic substitution?

Electrophilic Aromatic Substitution: Introduction. A key reaction of aromatic compounds is electrophilic aromatic substitution, where a C-H bond is broken and a new C-E bond (E being an electrophilic atom such as Cl, Br, N…) is formed.
