constitutional isomers

Constitutional isomersare compounds that have the same molecular formula and different connectivity. To determine whether two molecules areconstitutional isomers, just count the number of each atom in both molecules and see how the atoms are arranged. If both molecules have the same count forallof the different atoms,andthe atoms are arranged in different ways (theirconnectivityis different), the molecules will be constitutional isomers.
