Sn2 Reaction Lab Report
Experiment VIII was performed to analyze SN2 and SN1 using tertiary and primary substrates and use gas chromatography (GC) to examine the SN1 reaction. The product of the SN2 reaction was classified as n-butyl iodide by using infrared spectroscopy and gas chromatography mass spectroscopy and the product of the SN1 reaction was identified as of t-butyl chloride by using infrared spectroscopy and gas chromatography. For the SN2 reaction, 7.62 grams of n-butyl bromide, 20.0 grams of sodium iodide, and 79.1 grams of acetone were used to produce 3.12 grams of n-butyl iodide. The limited reagent was identified as n-butyl bromide and the theoretical yield of n-butyl iodide was calculated as 10.3 grams. The percent yield of this reaction was calculated

798 Words | 4 PagesResults The lab experiment was done in two parts, one with the NAND, NOR, XOR and Hex Inverters and the other with a 7483 full adder gate, both will verify the truth table when two input bits and a carry are added together. The circuits were built by examining the 1 bits through a K-Map to create a Boolean expression for the sum and carry. The Boolean expression for the sum was A⊕B⊕C and the carry as AB+BC_in+AC_in. From these two expressions, we notice that we must use two exclusive-ORs gates in the sum inputs for A, B, and C. For the sum, we have to use NOR and NAND (the only available gates from the lab manual).

To consider such observations, we need to do a process called additive smoothing or Laplace smoothing to smooth the categorical data. [9] In this case, we add 4 sequences: AAAAAAAAA, CCCCCCCCC, GGGGGGGG, TTTTTTTTT.

574 Words | 3 PagesExperiment 7 In this experiment we configured several DC circuits consisting of an emf and a network of resistors. The circuits were composed of a power supply, two DMMs, a circuit board, an SPST switch, and an assortment of known resistors along with one unknown resistor. We measured the current and voltage of the entire circuit as well as the potential drops across each resistor to determine the parameters of the circuit including the resistance, voltage, and current for each component.

362 Words | 2 Pages1. There are two ways of maximizing points in this experiment. The first one is that I should connect myself to a vertex that is in the biggest component and purchases immunization. Since the probability of being infected is based off of expected value, I would have less than 1% chance of getting infected. The second way is that I try to make myself stay in the second-largest connected component.
Sn1 Reaction Lab Report
2140 Words | 9 PagesIntroduction An unimolecular substitution reaction, SN1 reaction, has a two step mechanism that results in a halide group being displaced by a nucleophile1. In an SN1 reaction, the first step involves the leaving of a halide group to form a carbocation intermediate. This is the rate determining step, and it is also the slowest step. In the second step a nucleophile attacks a face of the the carbocation. Figure 1 displays this mechanism.

Various percentages of substrate concentration (5%, 15%, and 25%) was added to the reaction chamber and the Oxygen tube is filled with water and contained a water bubble at the top. The initial height of the water in the Oxygen tube was recorded. After 30 seconds, the total change was determined and recorded.

Sub-bands are formed by using the logarithmic spacing. The positions of these filters are equally spaced along the Mel frequency, which is related to the common linear frequency f by following formula: Mel (f) = 1125* ln (1+f/700) (3) Mel frequency is proportional to the logarithm of linear frequency and which is close to the human perceptual system. 2.5 Sub Fingerprint Generation:
Reaction Lab
928 Words | 4 PagesLab report: How does the surface area affect the rate of reaction ? Introduction The rate of a chemical reaction (or reaction rate) is a calculation of the total time needed for a reaction to take place, or how quickly the reactants are transferred into products in a chemical process. This rate can be measured in two methods. The first one is to measure the rate at which the reactants are used up per unit of time, while the second method is to measure the rate at which the products are formed per unit of time. There are several factors that affect the rate of a reaction.

In this experiment we will be illustrating the reaction between baking powder and vinegar and see what happens to the balloon that is attached to it. Hypothetically the reaction of the vinegar and baking powder will produce carbon dioxide which will inflate the balloon. If the more vinegar may happen that when more vinegar is added to the baking powder it may produce more carbon dioxide thus the balloons diameter increases.

How To Synthesize Turt-Butyl Chloride Sn2
213 Words | 1 PagesIn this experiment, the objective was to synthesize turt-butyl chloride via an sn1 reaction and use sodium iodide and silver nitrate reagents to test the reactivity (book cite). Sn1 stands for first-order nucleophilic substitution (book cite). A substitution reaction is when another atom replaces the halide ion (book cite). The other reaction that can take place is what’s called the elimination reaction. This involves a halide ion leaving with a different atom.
