The three prominent types of constitutional isomers are: Skeletal isomers (commonly referred to as chain isomers) Positional isomers (also known as regioisomers) Functional isomers (sometimes referred to as functional group isomers)
Isomerism : - The existence of two or more compounds having the same molecular formula but a different arrangement of atoms within the molecule.
There are 2 types of Isomerism :
# Constitutional isomers
# Stereo isomers
then, 3 types of constitutional isomers -
1. Skeletal Isomers - are molecules with the same molecular formula, but different arrangements of the carbon ‘skeleton’.
e.g. :- Pentane (C5H12).
2. Place Isomers (positional isomers) - Positional isomers differ from each other based on the position at which the functional group is attached to the molecule.
e.g. :- 1,4-Dibromobenzene (C6H4Br2).
3. Functional Isomers - Functional isomers are constitutional isomers bearing different functional groups.They contain different functional groups.
e.g. :- Acetone (C3H6O).
Also, 2 types of stereo isomers -
1.Enantiomer – also called optical isomer, that are mirror images of each other that are non-superposable.
e.g. : - dextro lactic acid.
2.Diastereomers -are defined as compounds which havebonded elements but which are nonsuperimposable, non-mirror images.
