E-Z Nomenclature

Introduction to E-Z nomenclature E-Z notation is used to name geometric isomers. It is an extension of cis-trans isomer. When none or most of the groups attached to the double bond are not same then in IUPAC system geometric isomers are notified or named with E or Z. For the notification of this type of isomers … Read more

Geometric Isomers

Geometric Isomers Definition Geometric isomerism is a kind of stereoisomerism. It is also known as cis-trans isomerism or E-Z isomerism. Geometric isomerism occurs due to the restricted rotation about carbon-carbon double bonds or carbon-carbon single bonds in cyclic compounds. Geometric isomers are the stereoisomers which differ from each other in the arrangement of groups with … Read more

Structural Isomers

Structural Isomers Definition Structural isomerism, or constitutional isomerism,  is a type of isomerism where isomers have same molecular formula but have different arrangements of atoms within the molecule. e.g. n-pentane, isopentane and neopentane are structural isomers. Types of isomerism Structural isomerism is of five types: Chain isomerism Position isomerism Functional group isomerism Metamerism Tautomerism 1. Chain isomerism … Read more
