Types of organic reactions

All the organic reactions can be classified into the following eight types: Substitution reactions Addition reactions Elimination reaction Rearrangement reactions Condensation reaction Isomerisation reaction Pericyclic...

Free Radicals

A free radical may be defined as an atom or a group having an odd or unpaired electron.These are generally produced by homolytic cleavage of...

Carbanions

Chemical species bearing a negative charge on carbon and possessing eight electrons in its valence shell are called carbanions. These are produced by heterolytic cleavage...

Carbocations

Most of the organic reactions occur through the involvement of certain chemical species.These are generally short lived and highly reactive and hence cannot be isolated.These...

Hyperconjugation Effect

The inductive effect of the alkyl group on a saturated carbon chain follows the order: (CH3)3C > (CH3)2CH- > CH3CH2-> CH3– When an alkyl group...

Resonance or mesomerism

The phenomenon of resonance is said to occur whenever for a molecule we can write two or more Lewis structure which differ in the position...

Inductive and Electromeric Effect

Fission of a covalent bond Homolytic fission If a covalent bonds breaks in such a way that each atom takes away one electron of the...

Electrophiles and Nucleophiles

In an organic reaction, the organic compound called the substrate reacts with a suitable attacking species called the reagent to form products. The formation of...

Stereoisomerism

Isomers which have same structural formula but have different relative arrangement or atoms or groups in space are called stereoisomers and the phenomenon is called...

Structural Isomerism

Isomerism Two or more compounds having the same molecular formula but different chemical and physical properties are called isomers and the phenomenon is known as...

Nomenclature of Simple aromatic compounds

Aromatic compounds contain one or more isolated or fused benzene rings.An aromatic compound consist of two parts : 1)Nucleus: The most ideal aromatic compound is benzene.It...

Rules For naming Alicyclic Compounds

The names of acyclic compounds are obtained by adding the prefix cyclo to the name of the corresponding straight chain hydrocarbons. 2) If two or...

Functional Or Characteristic Group

Hydrocarbons are the parent organic compounds.All other compounds are considered to have been derived from them by replacing one or more of their hydrogen atoms...
