Exposure may occur by breathing air contaminated with auto exhaust or gasoline fumes while refueling autos. Protection. MTBE is manufactured by reacting 2-methylpropene with methanol. Explain why low molecular mass alcohols are soluble in water . Why is the C—O—H bond angle in alcohols slightly less than the tetrahedral angle whereas the C—O—C bond angle in ether is slightly greater? 2. Er hat zum einen wegen seiner Verwendung als Antiklopfmittel in Ottokraftstoffen sowie zum anderen als Lösungsmittel in der organischen Chemie eine gewisse großtechnische Bedeutung erlangt. To prepare di (tert-butyl)ether by Williamson synthesis, we need tert-butyl halide (say bromide) and tert-butoxide (as sodium salt). tert-Butyl methyl ether is absorbed readily after inhalation exposure and ingestion, and is distributed rapidly in the organism. The structure of ethers was proved due to this chemical reaction. Summary Other designations. Water soluble. Books.
