A) lose electrons to form positive ions called cations.
Gas chromatography (GC) is a method of separating mixed compounds.
The separation will depend on each compound's retention time. Compounds with
higher molecular weights will elute out slower than those with lower molecular
weight. This is due to their difference in boiling points. The larger the
structure, the higher the boiling point.
