The phenomenon of isomerism occurs when two or more compounds have the same chemical formula but distinct chemical structures.
Isomers are chemical compounds with identical chemical formulae but differ in characteristics and atom arrangement in the molecule.
Characteristics of Isomers:
Isomers are molecules with similar chemical formulae but distinct structures.
They're important in air emission chemistry because even little differences in structure can cause dramatic changes in chemical and physical properties.
Constitutional isomers are molecules with varying connections, similar to basic bracelets with a different sequence of red and green beads.
The second category is stereoisomers. Stereoisomers have the same connection as stereoisomers, but the parts are arranged differently in space.
