Contrast this with stereoisomerism, where isomers have the same atoms in the same order and with the same bonds, but oriented differently in three-dimensional space. When Wöhler, in 1825, analysed his cyanic acid, and Liebig his quite different fulminic acid in 1824, the composition of both compounds proved to be absolutely the same, containing each in round numbers 28% of carbon, 33% of nitrogen, 37% of oxygen and 2% of hydrogen. When any two compounds have the same molecular formula but possess different functional groups, they are called functional isomers and the phenomenon is termed functional isomerism. See more.

In other words substances with the same molecular formula but belonging to different classes of compounds exhibit functional isomerism. A very similar type of isomerism results from replacement of a coordinated group by a solvent molecule (Solvate Isomerism), which in the case of water is called Hydrate Isomerism.The best known example of this occurs for chromium chloride (\(CrCl_3 \cdot … This contains 10 Multiple Choice Questions for Class 11 Test: Isomerism (mcq) to study with solutions a complete question bank. endobj Functional Isomers. %���� endobj Another example is the comparison of the pentene isomers: the double bond is located between cent- Isomerism definition, the relation of two or more compounds, radicals, or ions that are composed of the same kinds and numbers of atoms but differ from each other in structural arrangement (structural isomerism ), as CH3OCH3 and CH3CH2OH, or in the arrangement of their atoms in space and therefore in one or more properties. <> Structural isomers are isomers that have the same component atoms but they are arranged differently from each other. When isomerism is due to the difference in the arrangement of atoms within the molecule, without any reference to space, the phenomenon is referred to as “Structural Isomerism”.
