Describe how you will accurately prepare 10.00 mL of 0.100 M HCl solution using a 1.00 M HCl stock solution. In your response to this question, be very specific about the quantities of stock solution and deionized water to be used in the dilution and the...
Chemistry 2401 Experiment 7 Acid Catalyzed Dehydration of 3.3-Dimethyl-2-Butanol with Rearrangement Experiment 7 Pre-lab Assignment Dehydration of 3,3-Dimethyl-2-Butanol 1. Draw the structures of all the expected products from the following reactions: a) 3-methyl-3-pentanol + H = b)2-methylcyclohexanol + H - c) 2-methyl-2-butanol + H - d) 2,2-dimethylcyclohexanol + H = This reaction will give a complex mixture of products, since rearrangements can occur. Show the full mechanism for this reaction and how the possible products can form from the carbocation...
The purpose of this experiment is to synthesize a polymer using a Gilch polymerization of 2,5- bis(bromomethyl) - 1 -methoxy-4-(2-ethylhexyloxy) benzene, to investigate the polymer's photophysical properties, and to understand the mechanism of the polymerization reaction. Introduction Poly(p-phenylene vinylenes), or PPVS, are highly luminescent polymers that are used for a variety of commercial applications. Their general structure is shown in Figure . PPVS can be synthesized via a number of routes, including a Gilch polymerization reaction, which will be used...
