The process of changing a chemical compound into a different form that has the same atoms but a different arrangement.
Isomerization is an important process in organic chemistry that helps create different compounds from the same elements.
Isomerization → It is formed from "iso-" (from Greek "isos", meaning equal) and "meros" (from Greek, meaning part) and "-ization" (a suffix used to form nouns indicating a process). The term refers to the process of changing a compound into another compound with the same formula but a different arrangement of atoms, thus having equal parts in terms of composition but differing in structure.
Think of 'equal parts' ('iso-') that are rearranged ('meros') to form something new — that's what isomerization means.
