Fractional distillation is a process by which elements in a chemical mixture are separated into different parts, referred to as fractions, corresponding to their boiling points. Fractional distillation is used to filter chemicals and to separate mixtures to achieve their components. This quiz focuses on what is the first physical process in distillation and a compound containing only hydrogen and carbon called. Take this quiz and discover what you know or don't know about fractional distillation.
