(e)Once again the formation of carbon dioxide is an example of an oxidation, and the reactionrequires use of an oxidizing agent.2.41Two atoms appear in their elementary state: Na on the left and H2on the right. The oxidation stateof an atom in its elementary state is 0. Assign an oxidation state of 11 to the hydrogen in theOH group of CH3CH2OH. H goes from 11 on the left to 0 on the right; it is reduced. Na goes from0 on the left to 11 on the right; it is oxidized.2.42Combustion of an organic compound to yield CO2and H2O involves oxidation. Heat is given off ineach oxidation step. The least oxidized compound (CH3CH2OH) gives off the most heat. The mostoxidized compound HO2CCO2H gives off the least. The measured values are:CH3CH2OHHOCH2CH2OHHO2CCO2HkJ/mol13711179252kcal/mol327.6281.960.22.43–2.45Solutions to molecular modeling exercises are not provided in this Study Guide and Solutions Man-ual.You should use
