What alkenes are formed when attached alcohol is dehydrated with TsOH?Label the major product when a mixture results
Ethers (general formula R—O—R)have many important uses. Until recently,methyl tert-butyl ether (MTBE, right)was used as an octane booster and fueladditive for gasoline. It increases the oxy-gen content of the fuel, which reducesCO emissions. MTBE is synthesized bythe catalyzed reaction of 2-methylpropene with methanol.(a) Write a balanced equation for the synthesis of MTBE. (Hint:Alcohols add to alkenes similarly to the way water does.)(b) If the government required that auto fuel mixtures contain2.7% oxygen by mass to reduce CO emissions, how many gramsof MTBE would have to be added to each 100. g of gasoline?(c) How many liters of MTBE would be in each liter of fuel mix-ture? (The density of both gasoline and MTBE is 0.740 g/mL.)(d) How many liters of air (21% O₂ by volume) are needed at24C and 1.00 atm to fully combust 1.00 L of MTBE?
