How do dispersion forces determine the boiling point of a substance

How do dispersion forces determine the boiling point of a substance  

How do the relationship demonstrated by the graph and the geometry of the different hydrocarbons help to explain the effect the dispersion force has on molecules of different size  

How would you use your graph to predict the properties of similar but larger compounds, such as decane (Cio H22)  

In diamond, each carbon atom is bonded to four other carbon atoms. Network solids, such as diamond, are often used in cutting tools because of their hardness. 

How is electronegativity difference used in determining the type of bond that occurs between two atoms
