Ethanol (CH3Ch2OH) the intoxicant in alcoholic beverages, is also used to make other organic compounds. In concentrated sulfuric acid, ethanol forms diethyl ether and water.
a) if 56.4g of ethanol yields 34.8 g of diethyl ether, what is the percent yield of diethyl ether?
b) During the process, 45.0% of the ethanol that did not produce diethyl ether reacts by the side reaction. What mass of ethylene is produced?
