Background Information, Reactions and Safety Precautions Background Information In the reactions below, it involves alkenes, alkanes, alcohols, acids, and water. In the beginning of the experiments they are unknown and it is needed that a test is used to identify them. Alkenes are unsaturated compounds with a C=C double bond. The high electron density of the double bond makes alkenes more reactive than alkanes. The best way to test for alkenes is to use bromine which is used in one of the reactions below. Alkanes are generally unreactive. Alkanes contain only C-H and C-C bonds, which are relatively stron ang difficult to break. The similar electronegativies of carbon and hydrogen give molecules which are non-polar and do not mix with water. This is why water is not used to test for it. The functional group in alcohols is the hydroxyl group, C-OH. They can be classified as primary, secondary or tertiary depending on how many...
