Synthesis Of Azo Dyes Lab Report

In this lab we used a bunsen burner to heat our chemicals and create a chemical reaction.

In the Dyes and Crimes laboratory experiment, the phosphorescence, fluorescence, and chemiluminescence properties i.e. traits of several chemicals were examined using (UV) Ultraviolet lamp. Observations on color, intensity, duration of glow, etc. were analyzed to determine the traits of the several chemicals. Correspondingly, the author of the unsigned note was determined through ink extraction, (TLC) Thin Layer Chromatography, (UV-Vis) Ultraviolet-visible spectroscopy along with the Rf values for of each individual sample of ink compared to the unknown: the ink of the author on the unsigned note. Phosphorescence substances

In this class, we focused on Alzheimer's, specifically how it affected the person. I found myself especially drawn to the chemistry behind it and how the brain was altered in ways that couldn't be examined until the autopsy. Alzheimer’s is a disease that as of yet has no cure, but has the potential to affect a fair majority of the population in the future. In view of this, I want to approach potential treatments neurological diseases such as Alzheimer's and Parkinson’s from a chemical standpoint and attempt to find preventative measures if not a cure. With this in mind, my interests lie in both organic chemistry and biochemistry. I am interested in the use of organic synthesis to create new medically useful compounds. Moreover, I am interested in the neurological responses and biological effects of the newly created compounds and how said compounds are applicable in the medical

The hydrogen peroxide oxidizes the phenyl oxalate ester, resulting in a chemical called phenol and an unstable peroxyacid ester.

One of the most important things organic chemists do is synthesize new and complex structures from simpler structures by chemical reactions. The techniques done in

The conversion of succinate to fumarate took place in the citric acid cycle, where the reaction reduced FAD to FADH₂ that produced free electrons that enter the Electron Transport Chain. By using DCPIP, an alternate electron acceptor, the reaction of the dye was monitored through its color change. DCPIP is blue in its oxidized form and colorless in its reduce state form. To determine the

2. The synthesis of a new drug may require as many as 30 steps, some of which produce

The book talks about seventeen molecules that changed history. These molecules range from being used in food that people consume, in the form of salt to clothes that people wear in the form of dyes. Various fields where these chemical molecules play an important role have been covered and they include the biological as well as biochemical industries. The focus of this book review would be on the use of these chemical molecules in the line of medicine. Medicine is interconnected with our lives to such an extent that we cannot do without them nor their effects, hence this is the focus of this book review.

Among the seventeen molecules that were discussed in the book, I was especially drawn to the ones that are omnipresent and influential to our everyday lives. After a glance through the content, I picked dyes, what diversified our apparels with the colorings; morphine, nicotine, and caffeine, that the alkaloid molecules present in our foods and drinks; and salt, one of the most essential compound to our bodies.

This experiment explored the multi-step synthesis of synthesis acetylsalicylic acid commonly known as aspirin. A common procedure used in organic chemistry labs is multi step synthesis. this procedure involves a cascade of reactions that ultimately lead to a desire product. The series of reactions begins with commonly found or readily available reagents which are synthesized into products which can be used for a secondary reaction, and so on and so forth until the final desired product is synthesized (Ryerson Department of Chemistry, 2017).

Dyes are added to foods so they appear more appetizing to the consumer; oranges are supposed to be orange and apples are supposed to be red. In this experiment, students gained insight on how different wavelengths transmit different colors and how the absorbency of a solution impacts its visible color. Absorbance spectrums show how strongly something absorbs different wavelengths of light. Absorbency in different regions of the spectrum influences the color that we see. In this experiment, students used a spectrometer to measure the absorbance spectrum of different color food dyes and learned how different wavelengths result in different colors.

Writing reports in organic chemistry lab may differ from the way it’s done in general chemistry. One goal of this course is to introduce you to the record keeping methods used in research labs. Such methods are designed to organize experimental data in a format similar to that required for publication in major scientific journals. Here are some important considerations that apply in research settings. 1. Your work is unique, meaning that you might be the only person performing certain experiments. 2. Research is an ongoing process. The projects assigned to you will likely continue after you leave. People assigned to those projects will need

The main purpose of the food dye experiment was to identify the different food dyes; red, blue, and yellow; and their concentrations that make up the given liquid and use that data to recreate the liquids color profile. The liquid that was to be tested and recreated was Listerine mouthwash. To determine the food dyes present in the mouthwash use a UV-visible spectroscopy which will give the absorbances of each wavelength. With the absorbance find the concentration of each color dye by using Beer’s Law. To find the volume need for each dye use the equation M1V1=M2V2 to recreate the

Experimental: 1. Synthesis of alkyl azide (I-IV Scheme-1) To a stirred solution of alkyl chloride in DMSO (10ml) was added sodium azide (1.2 equivalent) at 80oC. The reaction mixture was stirred for overnight. After completion of reaction the solvent was distilled off and water was then poured into reaction mixture.
