Structural Isomers
One kind of isomerism occurs when the atoms are connected in different ways. For example, three different structures can be drawn for the hydrocarbon C5H12, which differ in the carbon skeleton of the molecules, as shown in Figure 1.1. The first of these structural isomers, pentane, has 2 methyl groups (- CH3) and 3 methylene groups (-CH2-); the second, 2-methylbutane, has 3 methyl groups, methylene, and a CH unit; and the third, 2,2-dimethyl-propane, has 4 methyl groups and a single C atom to which these are bonded..
