succeed academically. One of the biggest influences on students today is the media. It is obvious that shows like South Park‚ Beavis and Butthead‚ and The Jersey Shore have a negative impact on student’s goals or morals. Programs like Jackass and Nitro Circus make it seem like being a total moron and doing crazy stunts will ultimately get you paid. Unfortunately there are hardly any shows that portray academic success as the “cool” thing. Even shows that may seem harmless like Drake and Josh for

Introduction Discovered by Georg Wittig in 1954‚ the Wittig reaction is a robust organic synthesis method for preparing stereospecific alkenes. In general‚ Wittig reactions involve an aldehyde or ketone and a Wittig reagent (triphenylphosphonium ylide) and result in the formation of an alkene product and triphenylphosphine oxide (side product). Stereospecific alkene products can be synthesized by adjusting the reaction reagents and conditions. In the 60 years since the Wittig reaction was discovered

Immigrants were drawn to the land of opportunity to make a better life for themselves and their families. It was the Irish and Chinese that had a vast influence on the transcontinental railroad. Their hard work and perfection resulted in the early completion of the railroad. These workers faced many hardships and difficulties along the way such as discrimination‚ hazardous weather conditions and unleveled land but it did not hinder the fierce competition between the two groups. It was their methods

Learning Activity 1 Preparation of Acetanilide Abstract Recrystallization is a common method of purifying organic substances through the difference 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 heating water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes from the solution‚ molecules of other compounds
