PPT-Elimination Reactions

In addition to substitution alkyl halides can also undergo elimination reactions which lead to the formation of alkenes As with substitution reactions elimination reactions come in two mechanistic types. Structures and Properties. Halogen is connected to a tetrahedral carbon. The carbon-halogen bond is polarized with the carbon having a partial positive charge and the halogen having a partial negative charge. (. Set 2. ). Acknowledgments. National Science Foundation .
