“depository” in Freire’s Banking Concept of Education‚ but no experience is more relative than my Organic Chemistry class three years ago where I learned that problem-solving education is vastly superior to banking-education because it allows students to acquire true understanding of their world and the ability to reach consciousness. During the summer of 2009‚ I took a summer semester of Organic Chemistry at University of California Berkeley. When I first entered the lecture hall‚ there were masses

The mixture was shaken and left to settle‚ the organic layer was removed to an Erlenmeyer flask and the aqueous layer was extracted once more with dichloromethane (5ml) and then combined with the previous organic extract. The combined organic layers were dried with anhydrous sodium sulfate‚ transferred through a Hirsch funnel into a filter flask (25m) attached to an aspirator. Filter paper was

used in stating different compounds and sates of the carbon compound which are specially used in a particular branch of chemistry called the organic chemistry. Polymerase chain reactions are the specific reactions which take place between several carbon compounds under particular circumstances. These invariably tough reaction chains are a part of the study of organic chemistry and thus the chain reactions are considerably hard to remember or to be memorized. Many individual students can be found

VI. Results and Discussion In this exercise‚ the goal was to produce acetylsalicylic acid through the organic synthesis from the reaction of salicylic acid to acetic anhydride‚ the starting materials. Instead of using acetic acid‚ acetic anhydride was used as solvent since the anhydride reacting with water to form acetic acid tends to drive the reaction to the right. It results from the elimination of a molecule of water from two molecules of acetic acid (see Fig. 11.2). Figure 11.3 below

Not since German chemist Friedrich Wöhler demonstrated in 1828 that an organic compound‚ urea‚ could be synthesized from inorganic precursors‚ ammonium and cyanic acid (Kinne-Saffran and Kinne‚ 290)‚ has the line between organic and inorganic or‚ in this case‚ biology and chemistry‚ been blurred as it has been in Addy Pross’ book What is Life? How Chemistry Becomes Biology. In it‚ Pross dispels the traditional belief that life’s evolution and origin must be subdivided into a chemical phase followed

Melting Points Elizabeth McGrail Organic Chemistry I 25 January 2013 ABSTRACT The objectives of this lab are‚ as follows; to understand what occurs at the molecular level when a substance melts; to understand the primary purpose of melting point data; to demonstrate the technique for obtaining the melting point of an organic substance; and to explain the effect of impurities on the melting point of a substance. Through the experimentation of three substances‚ tetracosane‚ 1-tetradecanol and

Abstract Introduction The acylation of the α carbon position of a carbonyl group is one of the greatest breakthroughs that has benefited chemists in organic synthesis particularly when in need of building a carbon skeleton of interest in a molecule. For one to be able perform this acylation technique‚ there are two mar approaches which are employable. The first method involves the deprotonation of the α-Carbon atom which has a pKa known to be ̴20 through the use of a strong base for instance
