nucleophilic aromatic substitution reactions

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 chemical reactions of haloalkanes can be divided into four types: Nucleophilic substitution reactions Dehydrohalogenation Reactions with metals Reductio..

Electrophlic Aromatic Substitution - 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 e..

Aromatic carboxylic acids undergo electrophilic substitution reactions in which the carboxyl group is a deactivating and meta directing group. Aromatic carboxylic acids, however do not undergo Friedel - Craft's reaction..

Aromatic aldehydes and ketones undergo electrophilic substitution at the ring in which the carbonyl group acts as a deactivating and meta-directing grou..

Electrophilic Substitution Reaction - Aromatic aldehydes and ketones undergo electrophilic substitution at the ring in which the carbonyl group acts as a deactivating and meta-directing grou..

Electrophilic Substitution Reactions - All amino groups -NH 2 , -NHR, -NR 2 are most powerful activating groups in aromatic electrophilic substitution reactions are ortho and para directing. Aniline gets instantaneously brominated at all of the thre..

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. ..

Chemical Reactions - Nucleophilic Addition Reactions - Aldehydes and Ketones are highly reactive compounds. They undergo similar reactions because of the presence of a carbonyl functional group in both of th..
