Structure Effects and Ambient Influences on Properties

We give here a number of examples of empirical structure-property relations, and how they can be used to predict the effects of structure modifications and ambient conditions on properties. 

However, all the derivatives with two —OH and with —NH2 are completely miscible with water. 

A summary of this small roster of empirical structure-property relations on water solubility shows  

This set of working hypotheses can be used to guide explorations on how to make structure changes in other chemical species to influence water solubility. However, its reliability has to be tested, especially when extrapolated to materials that are far from these simple organic compounds. The verification also enlarges the database, and may lead to revisions of the hypothesis. 

The aromatic bonds are also shorter than the single bonds, and cyclic aromatics are more compact than acyclic paraffins thus, benzene has a higher density than hexane.
