Chain & Positional Isomerism: Same Formula, Different Shape!

The video tutorial explains isomerism, a phenomenon where compounds with the same molecular formula exhibit different physical and chemical properties. It discusses two main types: structural isomerism, which involves changes in the relative arrangement of atoms, and stereoisomerism, which involves spatial arrangement changes. Structural isomerism is further divided into six types, including chain and positional isomerism. Chain isomerism is characterized by different carbon skeletons, while positional isomerism involves changes in the position of functional groups or bonds. Examples are provided to illustrate these concepts.
