Define isomerism
Two or more than two compounds having the same molecular formula but differing in their physical and chemical properties are called isomers (Greek: iso = equal, meros = parts) and this phenomenon is known as isomerism.
existence of elements with same molecular formulae but different structural formalae is defined as ISOMERISM\xa0
The phenomenon in which carbon compounds with same molecular formula can be arranged in different structures is called isomerism and the structures are called isomers.\xa0
