WebNov 9, 2024 · The isomers can be divided into two large groups: structural (or constitutional) isomers and stereoisomers. We will first consider the structural isomers, which can be divided again into three main subgroups: chain isomers, position isomers and isomers of functional groups. Structural isomerism can quickly get out of hand in … WebStructural isomers come in three varieties: 1.functional group isomers, 2.chain isomers, and 3.positional isomers. 1)Functional Group Isomerism: -A functional group is a common grouping of atoms, such as O-H or C=O, that categorizes a molecule and that affects the molecule's chemical properties. WebApr 14, 2024 · Structural isomers have different connectivities between atoms, while stereoisomers have the same connectivity but differ in the arrangement of atoms in space. ⇒ What is the R,S system? The R,S system is a nomenclature system used to describe the absolute configuration of a chiral center in a molecule. crystal river manatee map
