Purpose: To synthesize 1‚2‚3‚4-tetraphenylnaphthalene through a two-step synthesis. The aldol condensation reaction between benzil and dibenzyl ketone forms 2‚3‚4‚5-tetraphenylcyclopentadienone‚ which then reacts with a benzene formed by anthranilic acid and isoamyl nitrate in order to yield 1‚2‚3‚4-tetraphenylnaphthalene. Reaction Equation A: Synthesis of 2‚3‚4‚5-tetraphenylcyclopentadienone: A solution of 4 capsules potassium hydroxide (0.5g) and 5mL anhydrous ethanol was prepared

Explanatory Synthesis There is a big gap of rich and poor people today‚ in this society‚ how the upper class and middle class people think about poor people‚ is it really just about money?

Immigration Reform Those that legally enter America do so because we are a land of opportunity. They are able to apply their skills and talents to better themselves. In the meantime‚ they are part of the population that finds better ways of doing things (technological advances). Technological advances increase everyone’s standard of living. Those that come here illegally are hired by firms because of the cheapness of their labor this is the reason illegal immigration needs to be dealt with. But

across America are families undocumented hoping for a better life. The United States is a country of opportunity‚ a land of the free and a home of the brave. That explains why the immigration reform should take an initiative and take action. There have been several beliefs as in who originated in America‚ like the founding population of today’s Native Americans. America’s diversity spans a wide range of different peoples from various parts of the world. Throughout my research U.S Immigration has been

of MPTP dramatically accelerates this process in the course of days and not years (Hanson et al.‚ 2015). Additionally consumption results in a reduction of glutathione content (Sian et al.‚ 1999). What have been good and bad consequences of the synthesis of MPTP? MPTP negatively affects the body by penetrating the blood-brain barrier and entering the brain cells. MPTP is not toxic‚ however when it oxidizes it forms MPP+ which is toxic. Toxic oxidation later reaches the extracellular fluid and

Synthesis of Acetanilide By: Rick Whitely April 9‚ 2013 Organic Chemistry Lab 1; Professor J. Hutchison Recrystallization is a common method of purifying organic substances through the differences in solubility at different temperature. In this experiment‚ acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heated water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes

fact that America is a melting pot for so many different cultures‚ races‚ and religions makes it unique in the world. The newcomers‚ both legal and illegal‚ fill labor shortages and provide new business opportunities. History shows they also bring ideas‚ vigor‚ and ambition. However‚ rising immigrant numbers and messy immigration policies have become a serious problem to gain control of. Although immigrants have contributed to America‚ the government should reform current immigration policies

SYNTHESIS OF ESTERS USING GREEN AND NON-GREEN CHEMISTRY Abstract Esters are a class of organic compounds with the general formula RCOOR’. Ester also contributes the flavor and aromas in fruits and flowers. The esterification reactions will use in the procedure‚ which are the interaction of a carboxylic acid with an alcohol‚ aided by an inorganic acid catalyst (H2SO4). Moreover‚ the green method will not use any catalyst but using heating source instead (microwave). Based on the comparison of
