Lee, Angie CHEM 221B, Section 05 F 9:00 am- 11:50 am September 30, 2015 Organic Chemistry Laboratory Procedure- Week 2 Experiment 1: Introduction to Microscale Laboratory Laboratory Exercise 1, Option A: Automatic Pipette 1. Weigh 3-mL conical vial (with cap and insert already on it) on a balance. a. Weigh to nearest milligram 2. Dispense .5 mL water into the already weighed conical vial, replace cap and face insert on its down side. a. Weigh vial once again, but now with water in it. 3. Determine

72). Freire’s explanation worries me because to know is not to know. Just because I could recognize different functional groups, which in the banking concept would make me a better student, did not mean that I could apply my understanding of organic chemistry to a real life situation because I hadn’t been taught to apply the information to

encourage students to study chemistry by arousing their curiosity. I also want students to appreciate the interdependence of chemistry in their daily life. My passion for teaching comes from my love of learning. Even though I work in a research laboratory I love to watch the lit-up face of my students the exact moment the explanation of some chemistry mechanism dawned on them. So, I want to create a learning environment where students are eager to learn about chemistry to understand the world around

to preform and monitor these reactions. The new discovery and development process can be now be accelerated, which leads to a new optimized transformation faster. This activation bond, carbon-hydrogen, is currently at the edge of synthetic organic chemistry. Carbon-hydrogen activation allows the chemist to perform unexpected disconnection, and it enables synthetic strategies. Over the past thirty years, the Heck reaction has become a fundamental metal catalyzed carbon-carbon bond, which is able

A blue litmus paper was used to test. The blue litmus paper turned red when tested. The flask with the solution was cooled again. The organic acid was then collected using vacuum filtration. Once collected, the organic acid was washed with cold water and air dried briefly. Lastly, the product was recrystallized from ethanol. The mass of the crude product, mass of p-methoxycinnamic acid and the melting point range of p-methoxycinnamic

Isomerization is the chemical process by which a compound is transferred into any of its isomeric forms. i.e., forms with the same chemical composition but with different structure or configuration and, hence, generally with different physical and chemical properties. An example is the conversion of butane, a hydrocarbon with four carbon atoms joined in a straight chain and is a branched-chain isomer, isobutane, by heating the butane to 100° C or higher in the presence of a catalyst. Butane and isobutane

by one or more planar rings of atoms joined by covalent bonds of two different kinds. The unique stability of these compounds is referred as Aromacity. Although aromatic has its origin from compounds characterized by its odor or fragrant, now, in chemistry, to compounds those have particular bonding arrangements that cause certain  (pi) electrons within a molecule to be strongly attached. They are often reflected in Heat of Combustion and in Hydrogenation. Benzene (C6H6) is the best known aromatic

Identifying an Unknown Solid Using Melting Point and Mixed Melting Point Data Shultz, Joshua T. Chemistry 2210L Results The experimenters inserted a capillary tube containing approximately 2 to 3 mm of benzoic acid into a manual Mel-Temp melting point apparatus. With the Mel-Temp dial set between 3 and 4, the temperature increased at a steady rate of approximately 2° C per minute from a plateau set at 90° C. The first appearance of liquid occurred at 119° C, and the benzoic acid completely

I strive to enhance the quality of human life through sound investigation and precise medical judgement. My earliest influence in the medical field stemmed from frequent visits to Children’s Hospital of Cincinnati diagnosed with chronic asthma. Fortunately, my unsolicited visits to the hospital opened a faucet of interest in medicine. I am fascinated by the human body and how the body responds in a variety of induced unfavorable conditions. With much consideration and educational preparation I have
