If another group has a different elution order than you, discuss your reasoning and come to a consensus. Once your group has agreed on an elution order and predicted fragment sizes, bring your intact molecules up to the front of the class and place them in the correct order. Fill in the table below with your predictions for the “masses” (# of blocks) of the likely fragments of each molecule.Should be related to bond strength and stability of molecules and fragments.Figure out where the weak points are within the molecule and evaluate which parts appear to be more exposed.Assume that RED has the lowest boiling point and YELLOW has the highest.Įlution order: 1 st_ RED _ 2 nd_ BLUE _ 3 rd_ YELLOW_ Predict the elution order of the three molecules following GC chromatographic separation.These will represent the molecular masses of your group’s three molecules. In the table below, record the number of individual blocks that make up each color. Within your group of three, assign and distribute a different color (RED, BLUE, YELLOW) “Duplo” molecule to each person. \)Įxercise = black text Key = blue text Instructor’s Guide = bracketed italicized text with yellow highlight
