- Structural Isomers: Alkanes One of the reasons for the complexity of carbon compounds is that it can bond (catenate) with itself. Oils are mostly made up of hydrocarbons, for 'saturated' compounds, these obey the formula CnH2n+2. The empirical formula (unlike benzene) will vary with n. Now we have established C is tetrahedral, how many structural (skeletal) isomers can we find for n=6, hexane C6H14 ? 1) Sketch all the isomers. What procedure did you use to make sure you didn’t miss any ? Do you think you could you do this now for heptane C7H16 ?! (Hint: 9 different ‘skeletal’ topologies) Note the number of possible isomers increases in highly exponential way. C10 – 75 isomers C15 – 4,347 isomers C20 - 366,319 isomers !!

Structural isomers are compounds with the same molecular formula, but different bonding arrangements or connectivities. In other words, the atoms are connected in a different order. For example, there are 2 different compounds with the molecular formula C4H10. They are given below: H H-C- H -H H H HHH H- H H-C -H Η ΗΗ H H Do you see how the atoms are bonded in a different order in the 2 structures? So they are structural isomers.
