In radical halogenations lab 1-chlorobutane and 5% sodium hypochlorite solution was mixed in a vial and put through tests to give a product that can then be analyzed using gas chromatography. This experiment was performed to show how a radical hydrogenation reaction works with alkanes. Four isomers were attained and then relative reactivity rate was calculated. 1,1-dichlorobutane had 2.5% per Hydrogen; 1,2-dichlorobutane had 10%; 1,3-dichlorobutane had 23%; and 1,4-dichlorobutane had 9.34% per Hydrogen.…

Pat 1 Synthesis of 4-aryl-6-indolylpyridine-2-carbonitriles and evaluation of their biological activity Synthesis of 6-indolyl-4-aryl-3-cyanopyridine-2-one (1a-e) Employing the MCRs approach and microwave irradiation, an equimolar amounts of aromatic aldehyde, 3-acetylindole, ethyl cyanoacetate were reacted with excess of ammonium acetate in one-pot, reaction, under the microwave irradiation, afforded a novel series of 4-aryl-6-indolyl-nicotinonitrile-2-one derivatives 1a-e. Ethylene glycol was used as a solvent and piperidine was employed as a catalyst during the microwave syntheses at a power of 250 W and 150 oC for a (15-20) min, scheme 1. All compounds were characterized by IR, mass, and NMR spectroscopy. The rate of reactions, and…

The Oxone epoxidation reaction is a two-step mechanism that includes forming the dioxirane first. The second step is using the dioxirane to attack the trans-anisole. The mCPBA reaction is a one step that forms the trans-anethole oxide.…
The Luminol first reacts with the hydroxide molecules to form two negative charges, or dianion. The dianion then reacts with oxygen to form a 5-aminophtalic acid and nitrogen gas. After, the oxygen forms with the hydrogen peroxide and the…
The Iodine Clock Investigation Introduction This is an investigation into the rate of a reaction and the factors that contribute to how fast a reaction will take place. Through the recording and analysis of raw data, this investigation also allows us to apply generally accepted scientific rules and to test them against results gained from accurate experimental procedures. Aim The aim of this experiment is to investigate the rate at which iodine is formed when the concentration and temperature of the reactants are varied, and to attempt to find the order and activation energy. The Chemistry 'THE IODINE CLOCK ' -…
The two essays, “Work and Workers in the Twenty-first Century" and "The Untouchables" bring out great points that everyone should take into consideration. One being that the work field is rapidly changing and people need to start focusing on their skills. Not only did they both address how it is changing but also how many more opportunities there will be, not just for certain people, but for everyone.…
Beveley Minett and Sandy McFarlane clicked on eBay and have never looked back. 1- The pair, both 43, were already seasoned seller trading tips with other users in one of the site‟s chat rooms when they first started communicating. Divorced mum Bev, from Worcs, remembers how she and Sandy, from Glasgow, were online rivals- until they saw photos of each other. Bev recall:” We both had our own little following of people who would ask us for help and there was a bit of rivalry between us. In fact, the very first time we communicated he had a right go at me for something and after that I gave him a bit of wide berth. There was certainly no flirting between us- if anything he was a bit mean and moody.” 2- Then they posted up pictures of themselves and suddenly Bev and Sandy saw a whole new side to each other. Shocked Bev, who has sold heaps of her unwanted clutter to buyers all over the country since first registering with the site, recalls:” I‟d never pictured he looked like he did and couldn‟t help thinking „He is a bit of alright‟”. Sandy, who runs his own company using eBay as a market place for IT components, was equally obsessed. He says:” I saw the picture of Bev and thought she was really good looking. I thought „I will have a bit of that‟”. 3- The couple began e-mailing each other more and more and soon they were chatting on the phone. After one conversation which lasted all through the night they decided they had to see each other in the flesh. So Sandy who is also divorced and has a nine-yearold son, Mathew, flew to the Midlands to see Bev. Bev, who has a seven-year-old son, Joel, remembers:” When I met Sandy at the airport I was very nervous. I was thinking „What am I doing? Shall I just run away now? What if he is the scary monster from hell?” 4- Bev says:” we just hit it off straight away. By the end of the weekend he didn‟t want to go and I didn‟t want him to go. We realized we didn‟t want to be without each other. Within about two weeks he had moved his…
