Observations of Demonstrations 1. Combustion of alcohols. Observe the color and characteristics of the flames: c. 2-propanol (CH,CHCH,) 1. OH Methanol (CH,OH) b. Ethanol (CH,CH,OH) a. What trend is observed as the number of carbons in the chain increases? Do think that it is possible that products other than carbon dioxide and water vapor are pro- you duced when these substances burn? What would make you suspect this?
