on 10 March‚ 2013 Introduction: This practical is meant to measure the rate of reaction of the hydrolysis of tertiary-butyl chloride –a colorless‚ liquid organic compound at room temperature that is sparingly soluble in water - in water/acetone and water/isopropanol mixtures. Since there are many influencing factors for the rate of reaction‚ all are kept constant but the intended variable: the solvents. If the reactant is more stabilized by interaction with solvent molecules than is the

reactions desire tertiary substrates most‚ followed by secondary‚ and lastly primary. Because the strength of the nucleophile is unimportant‚ an ionizing solvent is needed. Water is the best solvent‚ followed by methanol‚ ethanol‚ propanol‚ and lastly acetone. In experiment two‚ the tertiary 2-bromo-2-methylpropane was the most favored reactant followed by the secondary

Introduction: Doing laundry has been a common household activity for years. Whether the technology was beating the garments on rocks by the river or pushing buttons on programmed washing machines‚ this process depends on water and a mechanical action usually assisted by soap or detergent. The purpose of a detergent is to remove ordinary stains and other matter. More often than not‚ the soap/detergent agent holds stains in suspension as they becomes loose during the wash cycle‚ and are subsequently

acid) in all three positions linking to the glycerol molecule. 2. Trimyristin is soluble in ether and insoluble in acetone. Which part of the lipid molecule is responsible for this physical property‚ the glycerol or the fatty acid? Explain the observed solubility properties of trimyristin. The fatty acids are responsible for its solubility in ether and insolubility in acetone. The fatty acids are long non-polar hydrophobic carbon chains and can only dissolve in other non-polar solvent like diethyl

Raw Materials for 3M Super 77 Multipurpose Spray Adhesive In the wake of mass production‚ which started in the late eighteenth century as a result of the industrial revolution‚ consumerism has been on the rise in exponential terms. The high demands that human civilization puts on earth’s resources stems from consumerism‚ and as a society it is important to take a moment and think about the impacts each and every one of our material goods has. This impact can be traced within the lifecycle of a product;

Analysis of Oxygen bearing Organic compounds Abstract The Unknown sample in the experiment can be tested to yield results such as 1° (primary)‚ 2° (secondary)‚ 3° (tertiary) alcohols. Tests such as the dichromate test‚ Tollen’s test‚ Lucas test‚ DNPH test and iodoform test would be very useful in determining the type of alcohol that the unknown sample belongs to. In the experiment‚ the unknown sample underwent series of testing to identify what property of alcohol it belonged to and the result
