Figure 2 below shows the structures of the two antioxidants. Both antioxidants contain a benzene ring and a hydroxyl group. However‚ BHA has an extra polar ether group. As a result‚ BHA is a more polar antioxidant compared to BHT and therefore elutes prior to

Cyclohexane is a saturated hydrocarbon and cyclohexene is an unsaturated hydrocarbon due to the presence of double bond.Both hydrocarbons produce carbon dioxide and water during combustion test. When the oxygen is limited‚ the product will be carbon monoxide and water. The alkenes are highly flammable and burn readily in air‚ forming carbon dioxide and water. In this experiment‚ the combustion of cyclohexene burns in an orange flame and produces relatively high amount of black soot. The black soot
