Organic reaction

electrophilic aromatic substitution. As the term states, the experiments deal with the chemistry of six membered ring compounds and their transformations through electrophilic substitutions. This type of reaction transforms the aromatic compound by allowing various functional groups to be attached to it. The general process of this reaction is a hydrogen on an aromatic ring, most simply an arene, being replaced by an electrophile. The substitution sometimes requires the electrophile to be produced through reaction and a base might be required to remove the hydrogen from the aromatic ring. So overall the reaction takes place in three steps. The first step is the production of the electrophile that will be used in the substitution by reacting an electrophile containing compound and a catalyst. The second step is the reaction of the electrophile and an aromatic compound, which results in a cation intermediate. This step is a second order step, also called the rate-determining step. The final step is cation intermediate…

who were out on convoys or patrolling. I remember the day clearly when my Sargent died. There had been a patrol out doing a routine sweep of our area and he stepped on an IED, which basically turned him into pink mist. There was no body to recover. I remember standing at the left corner security post when the blast went off. The blast was large enough to kill him and open cause minor injuries to the other men around him. There was this sense of panic since there was nothing I could do but watch…

makeup is present in many different types of research. Monthon Thanutamoayong is a scientific researcher who focused on the identification of inorganic pollutants in drinking water through nanofiltration. Through this type of testing, the rejection of certain organic and inorganic compounds is described regarding their size exclusion and electrostatic effect. (Thanutamoayong, 2002). Through his experiment, he completed analysis tests using UV light and absorption as a means of identifying…

indoor air quality is pests. Dust mites and fragments of cockroaches are part of common household dust. Dust is easily disturbed by even the smallest movement, causing it to float in the air until it is inhaled or lands on another surface. Dust mites live off the dead organic material found in dust and contain an enzyme that, when in contact with humans, causes allergic reactions. Dust mites do not bite humans. Similarly, cockroaches contain a protein that initiates allergic reactions…

exists in the environment in many different forms, each of those forms having different chemical abilities that have the potential to influence human health (Lynch, 2014). Arsenic has the potential to impact human health and has been studied over the centuries (Lynch, 2014). The research that has been studied has determined that the chemical form of arsenic found in food products characterizes over 20 different arsenic species (Lynch, 2014). The focus on organic and inorganic arsenic has led to…

an essential ingredient to survive; yet, one of the more complicated things to produce. In the food industry, the market creates products designed around what the consumers want and needs. Although that may sound simple, it is rather more complex than that due to consumers wanting everything from convenient, non-genetically modified organisms (GMOs), paleo, organic, clean labels, gluten free, and affordable products. Each of these categories has either been a constant desire from the consumers…

Isolation and Antibiotic Resistance Testing of Delftia acidovorans from Organic Lettuce Pa Kou Thor Introduction Organic foods continue to be a health choice trend for many United States Americans as they are seen as the healthiest, natural and raw choice of food. However, there has been a growing concern of having antibiotic resistance bacteria existing on fresh organic produce. This combats the long-term thought that organic food, being free of chemicals and antibiotics, would not have…

purification of the crude esters through simple distillation was not. The yield at the end of the experiment was not 100% percent due to certain factors in the natural process of synthesis and the technical failures within the experiment. Because of this, future researchers are advised to add smaller amounts of NaHCO3 to avoid clogging of the separatory funnel. Also the product must be fully stratified, with only the organic and aqueous layer visible, before separation of these. In…

procedures, more environmentally friendly vehicles and energy resources, even our knowledge of the universe. We have gained so much, but there is still controversy on everything we do to gain more advances in everything we know. A big controversy is the talk on the food we eat. The huge deal today is about Genetically Modified Organisms more commonly known as gmos and the rival of organics. The latter of people today agree that gmo’s are bad and should be banned from existence, I’m here to give…

doctors should do more research to see the benefits of organic foods. I searched to find if eating organically could prevent, reverse, or stabilize diseases, and viruses? I also wondered how available options like these were at local and chain grocery stores. All of these questions lead me to searching the advantages and disadvantages to eating organically. II. The Search Results Organic food consists of meat, dairy, fruits and vegetables made without pesticides. Bright red, yellow, and deep…
