- 3 Ethers (general formula R—O—R,) have many important uses. Until recently, methyl tert-butyl ether (MTBE, below) was used as an octane booster and fuel additive for gasoline. It increases the oxygen content of the fuel, which reduces CO emissions.

- Ethanol, C₂H60, 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-methylheptane, C8H18, releases 1.306 × 10³ kcal of energy. How much energy is released during the complete combustion of 405 grams of 2- methylheptane? kcal Assuming the same efficiency, would 405 grams of ethanol provide more, less, or the same amount of energy as 405 grams of 2-methylheptane? more less the same amount Retry Entire Group 9 more group attempts remainingarrow_forwardCyclopropane decomposes fairly rapidly at moderate temperatures whereas cyclohexane is quite stable.
