Week 10- Constitutional isomers Constitutional isomers have the same molecular formula, but their atoms are bonded in different orders. These may be further distinguished as chain isomers, which differ only in hydrocarbon chain structure, positional isomers, which differ in the location of a functional group, and functional group isomers which differ in the nature of their functional groups. Typically chain and position isomers show only modest differences in their physical and chemical properties, while functional group isomers differ greatly from...
