HCl to form 2-chloro-2-methylbutane, and to understand Sn1 and Sn2 reactions, in terms of how they are different and why one is more likely to happen over the other. The OH group in 2-methl-2-butanol is attached to a tertiary Carbon, meaning the reaction should occur via Sn1, a two-step reaction, and Cl should replace the OH group, to form a tertiary halide. HCl was added to 2-methyl-2-butanol and then several extractions were done to purify the product. The percent recovery was calculated to be…

chemical structure LOR as shown in Fig. 1a allows the proton transfer with carboxylic acids to form a salt. Furthermore, N of the pyridine ring may also act as a hydrogen bond acceptor, allowing the formation of co-crystal when it binds to the hydroxyl group of carboxylic acids. Fumaric acid (FUM) is a dicarboxylic acid that is safe to use orally, and it’s widely employed as an excipient in salt or co-crystal formation. FUM (Fig. 1b) can improve the solubility of several drugs through the…

2.7 Styrene Butadiene Rubber Styrene Butadiene Rubber (SBR) belongs to the synthetic rubbers families that are derived from Styrene and Butadiene.[53] SBR is an aqueous dispersion of (25%) Styrene (CH2=CHC6H5) and (75%) Butadiene (CH2=CH-CH=CH2) copolymer as shown in Figure (2-1). The copolymerization of these two polymers may done by different ways. Mostly they copolymerized in an emulsion process, by dispersing a soap like surface acting agent where the materials are in water solution.[54]…

It is a group of diseases involving abnormal cell proliferation may or may not having the potential to invade other parts of the body as well.[20]. There are more than 100 types of cancer known so far which can affect the human population [21]. Thus it is evident…

Abstract A Friedal-Craft reaction was performed to synthesize 1,4-di-t-butyl-2,5-dimethoxy-benzene from p-dimethoxybenzene and t-butyl alcohol. The product of the reaction was filtered using a Hirsch funnel, before recrystallizing and filtering a second time. The recorded mass of the product was .08g and the melting point was 47-52.7 °C. Introduction1 This experiment was designed to practice working with electrophilic aromatic substitution reactions. Specifically, a Friedel-Craft reaction was…

Question: How does functional groups on ethane impact the exothermic energy released during the combustion of the compound? Hypothesis: Equipment: Thermometer Ethane Ethanol Ethanoic Acid Fire and a skewer Weighing scale Ceramic Container 400ml beaker Aluminum foil Lab coat apron Safety goggles Retort stand and ring clamp Procedure: Wear your lab coat / apron and your safety goggles. Prepare 100ml of water into a beaker then cover it with an aluminum sheet. Poke a hole through the…

Groups that have the highest degree of cohesiveness are Molen/family and college friends. Within these groups, I feel that I am bound to these members with a strong attraction because these groups are whom I feel closest to, most comfortable with, and I am more attached to them. I believe that Molen/family is the most functional group because within that group, we all have social roles that cooperate with each other and spread positivity. Despite that fact that we argue and disagree a lot, at…

fully immerse themselves in her narrative. Hayes touches upon several controversial topics in her narrative, particularly how socioeconomic status is denied to minority groups who don’t have functional literacy. Knoblauch dissected literacy into four components, as an ominous definition cannot be agreed upon. One component is functional literacy, the understanding…

Additionally, it states that nearly one half (41 to 44 percent) of adults in the US that have a minimal level of literacy perform in low skill jobs.With this knowledge, how well would a person with a minimal, if nonexistent education, perform on a simple functional literacy test? This lack of literacy then leads to the conclusion that it creates a gap-most of those who are literate can hold more or less stable jobs with a medium high salary,…

This is because each functional response has relatively different initial functional response pathways, even though they all are increasing. For analyzing mesozooplankton grazing we would have expected to see the data follow either a Holling type II or III functional response curve. For as Frost discusses in his paper mesozooplankton eventually reach a maximum saturation level, where it no longer…
