Define structural isomer chemistry
WebMay 20, 2024 · Structural Isomers have the same molecular formula but different arrangements of atoms. There are three types of structural isomers: chain isomers, functional group isomers and positional isomers. A skeletal isomer of a compound is a structural isomer that differs from it in the atoms and bonds that are considered to comprise the "skeleton" of the molecule. For organic compounds, such as alkanes, that usually means the carbon atoms and the bonds between them. For example, there are three skeletal isomers of pentane: n-pentane (often called simply "pentane"), isopentane (2-methylbutane) and neopentane (dimethylpropane).

WebGenerally the number of isomers increases. You can demonstrate this to yourself by drawing all possible structures for propane (1), butanes (2), pentanes (3), and hexanes (5). One way to think about this is as follows: Each carbon you add can attach to any of the carbons already present in any isomer of the molecule.

WebOptical isomerism is a type of isomerism where molecules have the same molecular and structural formulae, but are non-superimposable mirror images of each other. An example is butan-2-ol. It has four different groups attached to its second carbon atom.
