4.61 What is actually measured by the octane ratings of different grades of gasoline?
Alcohols are very useful starting materials for the production of many different compounds. The following conversions, starting with 1-butanol, can be carried out in two or more steps. Show the steps (reactants/catalysts) you would follow to carry out the conversions, drawing the formula for the organic product in each step. For each step, a major product must be produced. (See Exercise 62.) (Hint: In the presence of H+, an alcohol is converted into an alkene and water. This is the exact reverse of the reaction of adding water to an alkene to form an alcohol.) a. 1-butanol butane b. 1-butanol 2-butanone

A) 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 combustion of one mole of ethanol releases 326.7 kcal of energy.The combustion of one mole of 2-methylhexane, C7H16, releases 1.150×103 kcal of energy. How much energy is released during the complete combustion of 495 grams of 2-methylhexane ?------------- kcalAssuming the same efficiency, would 495 grams of ethanol provide more, less, or the same amount of energy as 495 grams of 2-methylhexane? --------- B) Combustion reactions are exothermic.
