INTRODUCTION The goal of this experiment was the synthesis of 3-nitrochalcone from 3-nitrobenzaldehyde and acetophenone as shown in Figure 1: Figure 1: Synthesis of 3-Nitrochalcone from 3-Nitrobenzaldehyde and Acetophenone Source: cnx.org The mechanism for the synthesis of 3-nitrochalcone is presented in Figure 2. The alpha carbon on the acetophenone is deprotonated‚ followed by the attack of the alpha carbon

My literacy skills began to develop in the many ways lots of people do. It first started through the typical bedtime stories by my parents. Later on it was developed even more when I got to school and teachers began to shape and mold my style of reading and writing. In my opinion the reason I developed my literacy skills was because of need. Everyone‚ who wants to be successful‚ needs to know how to read and write. With having older brothers and my oldest one being ten years older than me I became

Experiment 13: Synthesis of 1-Bromobutane An SN2 Reaction Experiment #13: Synthesis of 1-Bromobutane an SN2 Reaction Introduction: In order to synthesize 1-Bromobutane an alkyl halide must be present to undergo a nucleophilic substitution reaction of an alcohol. Since 1-butanol is a primary substrate it will undergo an SN2 reaction with sodium bromide in order to convert the alcohol group to water which is a better leaving group and will in the end produce 1-bromobutane. Experimentally

Why is Visual Literacy Important? Urayoan V. Rivera CGD 218 August 27‚ 2012 Instructor Vasquez Why is Visual Literacy Important? We can look at images and we are allowed to see and interpret and self-define what the image is. The image can be a drawing a photograph or even a textual display with a color background. We see these images on an everyday basis and at times we just take them for granted. What we don’t know until we learn is that its Visual Literacy. That every image that

received good feedback from my teachers concerning my seven subjects. Throughout these subjects (Math‚ Science‚ Indonesian‚ English‚ Visual art‚ HPE) I have displayed the seven PLP capabilities‚ but as always‚ there is still room for improvement. My literacy skills were shown through my English course in which the teacher said I am “able to write well-constructed paragraphs to develop an argument” and can “create her own justified interpretations.” Numeracy strengths were represented through advanced

Literacy was not something that I grew up seeing at home. Both of my parents‚ neither read nor wrote‚ but‚ one thing that I can recall was that my mother would sing nursery rhymes in Spanish and would even teach me the hand gestures that went along with the song. For example las vocales ( the vowels)‚ la Escuelita (the school) and so on. Even though both of my parents were not active readers‚ they always told me the importance of higher education. I have both bad and good experiences in primary

Synthesis of 1-bromobutane from 1-Butanol using the SN2 Reaction Abstract: The objective of this experiment is designed to study the synthesis of 1-bromobutane from 1 butanol using a SN2 reaction.. The product will then be analyzed using a flamed loop test by use of fire. Reaction Mechanism: CH3CH2CH2CH2—OH H+ CH3CH2CH2CH2— +OH2 Br- CH3CH2CH2CH2—Br + H2O 1-butanol

Literacy Macbeth essay Lady MacBeth and MacBeth are both characters deep in blood throughout the entire story‚ as MacBeth is at the beginning portrayed as a sort of nervous to kill the King at first‚ being his first murderous action. This entire act is sort of the stepping stone for MacBeth leading to his bloodthirsty lunacy. Kind of like a virgin serial killer making his first kill in a way. Although Lady MacBeth is also sort of portrayed to be new to the murderous bloodthirsty lunacy scene she’s

The article I chose is called‚ “Synthesis of a Genius” by George Kauffman and Steven Chooljian. The area of exploration and discovery that I chose was the synthesis of urea in chemistry. Urea was discovered by Friedrich Wohler‚ in 1828. This discovery ultimately changed the belief at the time that only organic compounds can be created from living
