Multiple laboratory techniques separate organic compounds by their different boiling points. Therefore, a useful skill is being able to predict relative boiling points based on the structures of the compounds involved in a reaction. Select the compound that should have the lowest boiling point, based on each compound's general description.
a. a large molecule containing only nonpolar C H bonds
b. a small molecule containing one polar C F bond
c. a small molecule containing only nonpolar C H bonds
d. a large molecule containing one polar N-H bond
