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 stereoisomerism. cis-trans isomerism is an example of stereoisomerism. Due to π-bonding between the two carbon atoms, the rotation around carbon-carbon double bond is prohibited and hence the geometry of … [Read more...] about Stereoisomerism

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 isomerism. It is of 2 types: 1) Structural isomerism 2) Stereoisomerism 1) Structural Isomerism : Compounds having the same molecular formula but different structures i.e. different arrangement of … [Read more...] about Structural Isomerism
Nomenclature For Di and Polyfunctional Aromatic compounds
1) When an aromatic compound contains two or more functional group, it is named as a derivative of the compound with the principal functional group at position 1. 4-Nitrobenzoic acid 2-Aminophenol 3-Acetylbenzonitrile 4-Iodo-2-methylphenol 3-Bromo-4-hydroxybenzoic acid 2) If all the functional groups present in the benzene ring are such … [Read more...] about Nomenclature For Di and Polyfunctional Aromatic compounds
Nomenclature of Simple Aromatic Compounds
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 is represented by a regular hexagon of six carbon atoms with three alternate single and double bonds. This is called the nucleus. The ring may be represented by any of the … [Read more...] about Nomenclature of Simple Aromatic Compounds
Rules For naming Alicyclic Compounds
(1) 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 more alkyl group or other substituent groups are present in the ring , their positions are indicated by arabic numerals 1,2,3,4 ....while numbering the carbon atoms of the rings , the substituent which comes first in … [Read more...] about Rules For naming Alicyclic Compounds
