Chem 201 Lab October 21‚ 2011 Lab #6: Preparation of 2-chloro-2-methylbutane – an Sn 1 Reaction Purpose The purpose of this experiment was to prepare an alkyl halide‚ 2-chloro-2-methylbutane by reacting 2-methyl -2-butanol (t-amyl alcohol) with hydrochloric acid. Alkyl halides are of wide interest because they are widespread and have diverse beneficial and detrimental impacts .The overall reaction is given below: Procedure 1 ml of 2-methyl-2-butanol was measured using 1 ml syringe and

Williamson Ether Synthesis specializing in producing ethers‚ it was ideal for this lab because of the alcohol and the alkyl halide used. After the synthesis and isolation of Gauifenesin was completed‚ the melting point ranges were observed and percentage yields were calculated to compare with the values of authentic guaifenesin and guaiacol. Reflux was used to synthesize Guaifenesin. Guaifenesin is an expectorant‚ meaning it helps loosen congestion in one’s chest and throat‚ making it easier to cough

The base catalyzed Knoevengael condensation of butyl cyanoacetate and corresponding aldehyde led to the forming Butyl 2-Cyano-(3‚5 dichloro-phenyl)-2-propenoate. The analyses that were used to prove its composition and structure

the design and construction of the end product. This test is usually done prior to any decision being made on the materials use. The theory behind tensile testing is to measure the stress-strain response of the material. By doing so you obtain the yield strength and ultimate tensile strength as some of the results and also provides information on how brittle/ductile the material is‚ which is vital in the future usage of the material in testing. In this test the aim was to perform tensile tests on

Fixed Income Zero coupon bonds Professor Anh Le 1 – Zero coupon bond and zero yields A zero coupon bond (or zero for short)‚ as its name suggests‚ is a bond that pays no coupons. It only pays the face value on the maturity date. Not surprisingly‚ sellers of zero coupon bonds have to offer them at a deep discount in order to sell them to the public. For example‚ a 30‐yr zero‚ face value $1‚000 could be selling for as little as $53.54. One question you may ask right now is: i
