HINT: Note that the solvent is a water and acetone mixture. The water makes the solvent mixture polar and protic, while the acetone is present to enhance the solubility of the organic molecule. Identify the nucleophile and consider the structure of the intermediate formed in the reaction. Can there be a rearrangement?

Pre lab
Introduction Your instructor has prepared an extract of chloroplast pigments from fresh green grass or fresh spinach. A blender was used to rupture the cells, and the pigments were then extracted with acetone, an organic solvent. Work- ing with one other student, begin this exercise by separating the pigments extracted using paper chromatography. To do this, you will apply the pig- ment extract to a cylinder of chromatographic paper. You will then place the ylinder in a jar...

I. Nylon 6-6 is a condensation polymer. The last two lab handouts pointed out that "condensation reactions are extremely common among a variety of organic functional groups." Pick two appropriate functional groups (your choice) and draw structures to show the condensation reaction between them. Identify the functional groups that are reacting, as well as the linkage formed by the condensation. 2. Rather than use a carboxylic acid for the nylon condensation, you'll use the more reactive acid chloride. This must...
