Here are the solutions to the questions: i) Draw and Name the structures of the two compounds. The molecular formula C_2H_6O can represent two functional isomers: an alcohol and an ether. 1. Alcohol: Ethanol CH_3CH_2OH (Structural formula: CH_3-CH_2-OH) 2. Ether: Dimethyl ether (or Methoxymethane) CH_3OCH_3 (Structural formula: CH_3-O-CH_3) ii) How can you identify the -OH group of the alcohol? The -OH group of an alcohol can be identified by its reaction with an active metal like sodium. Step 1: Add a small piece of sodium metal to the compound. Step 2: Observe for the evolution of a colorless gas. Step 3: Test the gas with a lighted splint. If the gas produces a 'pop' sound, it indicates the presence of hydrogen gas. The reaction is: 2CH_3CH_2OH(l) + 2Na(s) 2CH_3CH_2ONa(aq) + H_2(g) The evolution of hydrogen gas confirms the presence of the hydroxyl (-OH) group in the alcohol. Ethers do not react with sodium metal.
