How are alkenes made from alkanes
WebDienes are prepared from the same reactions that form ordinary alkenes. The two most common methods are the dehydration of diols (dihydroxy alkanes) and the dehydrohalogenation of dihalides (dihaloalkanes). The generation of either an isolated or conjugated system depends on the structure of the original reactants.

WebAlkenes also form from the loss of both X's of a 1,2-dihaloalkane (Figure 9.13). Figure 9.13 These dehalogenation reactions do not involve bases. They use metals such as Mg or Zn that react with the halogens (Cl, Br, and/or I) to form metal salts such as MgX2 or ZnX2 (Figure 9.14). Figure 9.14 WebAlkenes contain a double bond that is composed of one sigma and one pi bond between two carbon atoms. The sigma bond has similar properties to those found in alkanes, while the pi bond is more reactive. The carbon atoms in the double bond are sp 2 hybridized, forming a planar structure.
