Bond polarity covalent bonds

We know that the three types of chemical bonds that exist between atoms are non polar covalent bonds, polar covalent bonds and ionic bonds. We are already familiar with the idea that it is helpful to think of these as making up a bonding continuum. Non polar covalent bonding lies at one end of the continuum and ionic bonding at the other polar covalent bonding lies between these two extremes. 

The difference between the electronegativity values of the two atoms involved in creating a chemical bond explains the ideas of bond character, bond polarity, covalent bonds, and ionic bonds. Figure 9.2 illustrates these concepts. 

This chapter provides a substantial introduction to molecular structure by coupling experimental observation with interpretation through simple classical models. Today, the tools of classical bonding theory—covalent bonds, ionic bonds, polar covalent bonds, electronegativity, Lewis electron dot diagrams, and VSEPR Theory—have all been explained by quantum mechanics. It is a matter of taste whether to present the classical theory first and then gain deeper insight from the...

Polar reactions occur because of the electrical attraction between positive and negative centers on functional groups in molecules. To see how these reactions take place, let s first recall the discussion of polar covalent bonds in Section 2.1 and then look more deeply into the effects of bond polarity on organic molecules.
