Comparative Investigation of Organic Compounds Tristan Duane G. Lacson‚ Lara Elize T. Lamigo‚ Maria Mikaela L. Laysa‚ Christian Gerard G. Lee and Karen L. Li Group 6 2C Pharmacy Organic Chemistry Laboratory ABSTRACT In order to differentiate the organic compounds. The group tested the compounds using the information based on their instinsic physical properties‚ behavior in ignition‚acidity and basicity and their infrared spectra. The physical properties were noted by the reaserchers by

This paper is an analysis conducted on Nucleic Acids through a variety of tests specifically‚ Dische‚ Murexide‚ Wheeler-Johnson and Phosphate Tests in order to exemplify structural features of nucleic acids as well as identify the principle involved in each chemical test. Different procedures and different test compounds were applied‚ and results were noted as for changes in colors of precipitates or solutions. For Dische Test‚ light blue was obtained for RNA and dark violet for DNA. For Murexide

Harvard Business School 9-792-060 Rev. April 28‚ 1993 Acid Rain: The Southern Company (A) Early in 1992‚ managers at the Southern Company were reexamining their strategy for complying with the acid rain provisions of the 1990 amendments to the Clean Air Act. The Southern Company was a holding company; its operating units were electric utilities in Georgia‚ Alabama‚ Mississippi‚ and Florida. The largest Southern subsidiaries‚ Georgia Power and Alabama Power‚ provided most of the electricity

How Acetylsalicylic Acid was Discovered Acetylsalicylic Acid in its earliest form was a powder for the bark and leaves of the willow tree. Hippocrates‚ who lived sometime between 460 B.C. and 377 B.C‚ founded it. This “Miracle Drug” that was able to relieve pains was later looked into with further detail by Johann Buchner. He isolated a tiny amount of bitter tasting yellow‚ need- like crystals‚ and called salicin. By 1829 French Chemist Henri Leroux had improved the extraction procedure to

is dangerous. There could be a symbol when you are in a science lab an example of this is a hazard symbol stating that there is acids in the laboratory .There are lots of different symbols used to warn people about lots of different things. If there is a hazard symbol telling you not to do it then don’t because it is very likely that you will get hurt especially if acid goes into your skin. Level 3 (continued) There are even symbols when you are going to school. It is there so it tells you to

HYDROLYSIS OF ESTERS Anhydrous alkanoic acids react with alcohols in the presence of heated sulphuric acid (H2SO4) to form an ester and water. This process is known as esterification. This can be represented by the equation: Alkanoic acid + Alcohol (means reversible eq) ester + water Esters occur naturally in fruits and flowers and are described as oily‚ sweet smelling liquids. Vegetable oils and animal fats are esters of long-chain acids. Esters can undergo a range of reactions and

methanoic acid:- Br2 (aq) + HCOOH (aq) ↓ 2Br- (aq) + 2H+ (aq) + CO2 (g) Bromine in aqueous solution is orange-yellow‚ but all the products and the methanoic acid are colourless. The colour gradually fades as the reaction proceeds. In this experiment we wish to determine the order of the reaction with respect to bromine. By using a concentration of methanoic acid which is 10 times greater than that of the bromine we can assume that the concentration of methanoic acid is constant

experiment‚ the three processes of extraction‚ sublimation and recrystallization will be used to separate a mixture of salicylic acid and naphthalene. The first part of extraction will be to separate the salicylic acid from the naphthalene using diethyl ether and aqueous sodium bicarbonate. The naphthalene will reside in the ether and be the top layer‚ while the salicylic acid resides in the sodium bicarbonate bottom layer. The two solutions will be separated and a solid crude substance will be collected
