Friedel-Crafts acylation is a classic organic reaction used to introduce an acyl group onto an aromatic ring. Here's a general overview of the Friedel-Crafts acylation experiment: Objective: To perform a Friedel-Crafts acylation reaction and synthesize an aromatic ketone. Materials: Aromatic compound (typically benzene or a substituted benzene derivative) Acylating agent (commonly acetyl chloride or benzoyl chloride) Lewis acid catalyst (usually aluminum chloride, AlCl₃) Solvent (...

BIOS 135 LAB REPORT FORMAT FOR MODELCHEM LABS I. Title Crude Oil Distillation Week 3 iLab II. Introduction Crude oil is the combination of gasoline, kerosene, lubricating oils, and other non-volatile liquids. In the following lab, we will be conducting a distillation experiment of crude oil. We should be able to observe how the chemical properties of the components of crude oil influences temperature at which it distills out of the crude oil. With distillation, we are able to remove i...

If a person drank a large quantity of hypersaline ocean water, the person could die because absorption of salt into the blood will cause it to become -Hypertonic compared with the cytosol of the bodies cells, causing osmosis of water out of the cells -If a cell is placed in an environment that contains a higher concentration of solutes than the interior of the cell, we call this environment hypertonic. When a cell is placed in a hypertonic solution, the solution is relatively solute-rich, whil...
