Sketch Observations of Demonstrations 1. Combustion of alcohols. Observe the color and characteristics of the flames: a. Methanol (CH,OH) b. Ethanol (CH,CH,OH) c. 2-propanol (CH,CHCH) OH What trend is observed as the number of carbons in the chain increases? Do you think that it is possible that products other than carbon dioxide and water vapor are pro- duced when these substances burn? What would make you suspect this? CH,CHOH(1) + 3 O(g)-2 CO(g) + 3 HO(g) (Combustion of ethanol) 2. Bromination of vegetable oil. What happens when the vegetable oil is added to the test tube containing the bromine? REPORT SHEET 185
