Discuss alkene isomers. Show structurally why alkene isomers will only begin with a minimum of 4 carbons. Exhibit, using 1-butene as the hydrocarbon, why there are 4 isomers when the formula's indicate a maximum of 3.
Write the chemical reactions which occur during addition reaction of halogens or halogen halides. Indicate why the concentration of halogen will determine the additions formula of the alkenes. Discuss hydrogenation with hydrogen as the reagent. Indicate why hydrogenated oils are solids and act like a preservative. Discuss the Markovnokov rule, and show examples.
