Synthesis of Butyl Benzoate Using Phase Transfer Catalysis The objective of the experiment is to synthesize the butly benzoate by nucleophilic substitution and characterize it by IR spectroscopy. The percent yield of the final product is determined after the synthesis. Procedures: 2.0 mL of 1-bromobutane‚ 3.0 g of sodium benzoate‚ 5.0 mL of water‚ 4 drops of Aliquat 336‚ and a boiling stone were placed in a 50mL round-bottomed flask. The reaction mixture was refluxed for 1 hour and the flask

The kidneys are a pair of fist-sized organs located outside the peritoneal cavity on each side of the spine. The kidney is a highly specialized organ that maintains the internal environment of the body by selectively excreting or retaining various substances according to specific body needs. The process of urine formation and adjustment of blood composition involves three

Questions and Hypothesis: Seed germination‚ plant growth‚ and sprouting of leaves are affected by several factors: supply of nutrients‚ water‚ exposure to sunlight‚ and conditions of surroundings. Due to certain stimuli in the surroundings plant “hormones” cause plants to behave in ways that ensure the most efficient use of resources while preserving the most energy. One stimulus to consider‚ is the exposure of plants to sunlight; when plants are just sprouting and are underground‚ the sti

Engineering Laboratory (Lab) Report Department of Engineering Faculty of Engineering and Science‚ University Tunku Abdul Rahman (UTAR) 1. Introduction Laboratory (Lab) reports are the most frequent document written by engineering student. These reports can contribute a significant amount of marks and yet little time or attention is devoted in understanding on how to write them well. The aim of this document is to provide a general guideline on writing a lab report. A lab report should not be

CHEMISTRY LAB REPORTS How to Write a Lab Report Lab Reports gives the explanation of the experiment done Lab reports are an essential part of all laboratory courses and usually a significant part of your grade. If your instructor gives you an outline for how to write a lab report‚ use that. Here ’s a format for a lab report you can use if you aren ’t sure what to write or need an explanation of what to include in the different parts of the report. A lab report is how you explain what you did

ELEC 202 LAB 1 REPORT INTRODUCTION TO LABORATORY INSTRUMENTS AND RESISTIVE CIRCUITS Objectives: The aim of the first experiment is to become familiar with lab instruments‚ get an idea about their working structure and how to use them when necessary. In addition to that in the first part of the experiment our aim is to read color codes of resistors and get idea about how to use multimeter for resistor measurements. In the second part of the experiment our aim is to see the operation of

Batteries‚ Resistance and Current “Battery-Resistor”: Check “show battery” and “show cores”‚ watch what happens‚ adjust some variables 1. Why do electrons (blue dots) move? Draw a diagram of the battery‚ label the flow of electrons. The flow of current (+) is opposite; draw this and note if toward or away from + terminal of the battery. The blue dots indicating the electrons move because there is a voltage across the battery in which the electrons flow away from the positive terminal

Introduction In unit 7.3 the experiment tested the ability of lactase to specifically bind and interact with lactose compared to maltose. In unit 7.4 the experiment tested the role‚ if any‚ that metal ions have on the activity of lactase. My hypothesis for unit 7.3 was knowing that lactase is specific for lactose‚ lactose will separate into galactose and glucose‚ as maltose will not change (153-155). Lactase should like lactose. For unit 7.4 my hypothesis was that EDTA will remove the ions‚ and
