24 CONSTITUTIONAL ISOMERS AND NOMENCLATURE
There are different types of isomers Isomers that differ in the connectivity of their atoms, such as butane and isobutane, are called constitutional isomers or structural isomers Recall (Sec 1 3) that connectivity is the order in which the atoms of the molecule are bonded The
