Classification According to Molecular Framework

Now that we have described single covalent bonds and their geometry, we are ready to tackle, in the next chapter, the structure and chemistry of saturated hydrocarbons. But before we do that, we present a brief overview of organic chemistry, so that you can see how the subject will be organized for study. 

The three main classes of molecular frameworks for organic structures are acyclic, carbocyclic, and heterocyclic compounds.
