Stereoisomerism is defined as the type of isomerism in which compounds possessing the same molecular formula and same structural formula, differ in their properties due to difference in the arrangement in space of their atoms in the molecule. Structural isomers are those isomers in which the compounds possessing the same molecular formula differ in their properties due to the difference in the linkage of atoms inside the molecule, i.e., due to a difference in their structures or bonding. Isomerism is broadly of two types, that is, structural isomerism or constitutional isomerism, and stereoisomers. The flexibility of the angles allows for. Due to the presence of a carbonyl center, esters have 120 C-C-O and O-C-O angles, and the functional groups of these esters are flexible. Esters are named with the suffix ‘-ate’ by the IUPAC. Thus, it is a functional isomer of ester. Esters contain a carbonyl group which is then attached to an oxygen atom to form the functional group. Which of the following is the functional group of ester None of the above OCH represents the functional group of aldehydes. sulfoxide (DMSO) as the methyl source exhibits a broad substrate scope and excellent functional group tolerance. Let us consider the ester ethyl acetate, which has four carbon atoms and is given as $C$. So, to check if functional group isomerism is shown, we must check the compounds of the given functional groups having equal numbers of carbon atoms. For more Chemisty practical, please press the following link. Functional isomerism is that type of isomerism in which the compounds possess the same molecular formula but the functional groups attached are different.įunctional isomerism is seen when substances having different functional groups have the same molecular formula.
