aromatic nucleophilic substitution

In this type of substitution, atom or group of atoms in the molecule is replaced by a nucleophile. These can be either S N 1 (substitution, nucleophilic, unimolecular) or S N 2 (substitution, nucleophilic, bimolecular) type. In the S N 1 ..

The nucleophilic substitution reactions can be classified into two types: First is the S N 1 reaction (substitution nucleophilic, first order). This type of reaction proceeds in two steps as: The first step is slow and is the rate-determining step. As ..

The -OH group attached to the benzene ring in phenol activates, it towards electrophilic substitution. It directs the incoming group to ortho and para positions in the ring as these positions become electron rich due to electronic effect (also mesomeric effect) caused by -OH group. The or..

Chemical Properties - Nucleophilic Substitution Reactions - The chemical reactions of haloalkanes can be divided into four types: Nucleophilic substitution reactions Dehydrohalogenation Reactions with metals Reductio..

Nucleophilic substitution reactions In the C-X bond there is a partial positive charge on the carbon atom and negative on the halogen atom. Thus nucleophilies attack the electron deficient carbon resulting in the displacement of the weaker nucleophile, the..

Nuclear Substituted Compounds When the functional group or any substituent, in aromatic compounds is directly attached to the benzene ring, it is a called nuclear substituted compound. Such compounds are named as the derivatives of benzene under the IUPAC ..

Direct chlorination or bromination of benzene or other aromatic hydrocarbon gives chloroarenes and bromoarenes. These reactions are carried out in the presence of Lewis acids such as ferric or aluminium halides (FeCl 3 , FeBr 3 , AlCl 3 ) in the dark, at ordinary temperatures (310-320 ..

Aromatic compounds can be directly nitrated using a mixture of concentrated nitric acid and sulphuric acid. This reaction is an example of electrophilic substitution of benzene. The electrophile is a nitroni..

Aromatic compounds are those, which resemble benzene in chemical behavior. These compounds contain alternate double and single bonds in a cyclic structure. They undergo substitution reactions rather than addition reactions. This characteristic behavior is called aromatic..

Aromatic compounds where the functional group is present in the sidechain of the ring are called sidechain substituted compounds. Sidechain substituted compounds are named as the phenyl derivatives of the corresponding aliphatic compound..
