structure include; IR spectroscopy‚ thin layer chromatography (TLC)‚ and CHN analysis. A radical copolymerization reaction was conducted‚ with the initiation by radical initiator 1‚1’-azobiscyclohexanecarbonitrile. CHN analysis‚ IR spectroscopy‚ and Proton NMR analysis were used to prove its composition and structure. 1. Introduction The American Chemical Society databases were investigated through Scifinder Scholar Version X to find any information about Butyl 2-Cyano-(3‚5 dichloro-phenyl)-2-propenoate

Esmeralda Curiel Organic Chemistry October 21‚ 2014 Experiment 41- 1‚4-Diphenyl-1‚3-Butadiene INTRODUCTION The study of the Wittig Reaction is important because it is often used to form alkenes from carbonyl compounds. The purpose of this experiment is to isolate the trans‚ trans-1‚4-diphenyl-1‚3-butadiene‚ which is formed by a Wittig reaction along with the cis‚ trans isomeric diene. The reaction is carried out in two steps. First the Wittig salt is obtained through a simple nucleophilic displacement

Mr. Brown all your tests look ok. Your triglycerides are at 145‚ cholesterol 210‚ hdl 33‚ and ldl 160. Triglycerides are chemical compounds digested by the body to provide it with the energy for metabolism. Triglycerides are the most common form of fat in the body. They are the main ingredient in vegetable oils and animal fats. Cholesterol is a soft‚ waxy substance found in all of your body’s cells. Your body needs cholesterol in order to work properly. This is because your body uses it to hold
