👉 Stereoisomerism is a molecular property where two different molecules have identical structural formulas but differ in their chemical properties. This can occur due to the presence of a diastereomer, an isomeric form that is not identical to its parent molecule. For example, in ethane (C2H6), both propyne and isobutene are stereoisomers because they have identical structural formulas but differ in their molecular properties. Stereoisomers can be produced through various
