To conclude... a synopsis of electrophilic addition reactions

Electrophilic addition to double bonds gives three-membered ring intermediates with Bt2, with Hg2+, and with peroxy-adds (in which case the three-membered rings are stable and are called epoxides). All three classes of three-membered rings react with nucleophiles to give 1,2-difunctionalized products with control over (1) regioseledivity and (2) stereoselectivity. Protonation of a double bond gives a cation, which also traps nucleophiles, and this reaction can be used to make alkyl halides. Some of the sorts of compounds you can make by the methods of this chapter are shown below. 

The orbital arguments in this chapter are also treated in Molecular Springer, 2007, chapter 5, treats both elimination and addition Orbitals and Organic Chemical Reactions Student Edition by Ian reactions.
