12. At most service stations, patrons can select their grade of gasoline. The different grades of gasoline are classified based on the octane rating of each fuel. From a chemical point of view, analyze the significance of octane ratings in the fuel industry. Be sure to cite your sources! Hint: Refer to page 392 in your textbook Your response should include an explanation of octane numbers a discussion of the importance of octane rating identifying how the octane rating of a fuel is adjusted

Describe the products that result when hydrogen (H2) is added to alkenes, alkynes, aldehydes, and ketones. You might review Chapter 12 briefly.
Why are octane numbers of gasoline different? what process affects them?
Why are the first three alkanes (methane, ethanr, and propane) are not included as a major component of gasoline? What prevents them from being part of the mixture?
[Review Topics] [References] Use the References to access important values if needed for this question. Ethanol, C2H6O, is most often blended with gasoline - usually as a 10 percent mix - to create a fuel called gasohol. Ethanol is a renewable resource and ethanol-blended fuels, like gasohol, appear to burn more efficiently in combustion engines. The heat of combustion of ethanol is 326.7 kcal/mol. The heat of combustion of hexane, C6H14, is 995.0 kcal/mol. How much energy is released during the complete combustion of 460 grams of hexane ? kcal Assuming the same efficiency, would 460 grams of ethanol provide more, less, or the same amount of energy as 460 grams of hexane?

Use average bond energies (table in the hint) to compare the combustion energies of ethane, ethylene, and acetylene. Calculate which of these hydrocarbons releases the most energy per gram. AU(per gram ethane) AU(per gram ethylene) AU(per gram acetylene) kJ/g kJ/g kJ/g These estimates indicate that ✓releases slightly more energy per unit mass than others. Remember that average bond energy calculations provide estimates, not exact values.
