Alcohols Used as a Gasoline Additive or Substitute Are Often

question 46

Multiple Choice

Alcohols used as a gasoline additive or substitute are often called biofuels. Similar organic compounds derived from vegetable oils and fats are called biodiesels, which are not alcohols but another class of organic chemicals called esters. Qualitatively compare the combustion energy content (kJ/g) of the four-carbon alcohol, butanol (CH₃CH₂CH₂CH₂OH) , with the energy content (kJ/g) of the four-carbon ester, ethyl acetate (CH₃COOCH₂CH₃) .

• A) Ethyl acetate has less energy/mass than butanol.
• B) Ethyl acetate has more energy/mass than butanol.
• C) The two compounds have roughly the same energy/mass.
• D) These are not two different compounds and so must have the same energy/mass.
• E) There is no basis for determining this without some form of enthalpy values.
