    Infrared Spectroscopy is used to identify molecules by giving structural information about a molecule. Based on the knowledge that CH bonds have an absorption rate of 3000+-100cm-1 and that C=O bonds (carbonyl groups) have a 1700+- 100cm-1 absorption rate. I was able to locate these types of bonds on the Infrared Spectroscopy reports done by Dr. Yamaguchi. I don’t have enough expertise on how to decipher the other peaks and valleys in the report and

    Separation of a Carboxylic Acid from a Neutral Compound by Extraction Reference: Smith‚ Chapter 2 (Acids and Bases) Introduction Carboxylic acids and phenols are two families of organic compounds that contain carbon‚ hydrogen and oxygen‚ and also react with water to yield an excess of hydronium ions over hydroxide ions. Pure water has a pH of 7‚ which means it has a hydronium ion concentration‚ [H3O+] of 10-7 M (M = molarity‚ moles/Liter). The hydronium ions in pure water come from the self-ionization

    used in organic chemistry‚ not only as solute but also as intermediate to synthesize halide‚ alkene‚ ether‚ aldehyde and ketone etc. In laboratory‚ an important method of synthesizing alcohol is though the addition reaction of Gridnard reagent and carbonyl compound‚ whereas aldehyde is the most reactive and then to ketone or ester. Primary alcohol is produced through reaction between Gridnard reagent and formaldehyde or ethylene oxide or alcohol halide; secondary alcohol is produced using Gridnard

    EXPERIMENT 5- A FISCHER ESTERIFICATION SYNTHESIS OF PEAR OIL One of the major uses of Esterification (C(=O)-C-R) is forming compounds with different odors which can be used to make different synthetic and natural flavorings.  Using the chemical and physical properties of organic compounds‚ an ester was catalyzed from the reaction of a carboxylic acid with an alcohol‚ producing an odor similar to that of pear oil. The mechanism of this Fischer- Esterification process is outlined as follows:

    are one of these chemical compounds that are found abundantly in the environment. Phthalates belong to a family of chemical compounds or substances which are based on a benzene ring (a six carbon membered compound)‚ to which is attached a pair of carbonyl groups in consecutive positions on the benzene ring (Sheeba et. al.). They are a family of industrial compounds with a common chemical structure‚ dialkylor alkyl arylestersof1‚ 2-benzenedicarboxylicacid. They are usually clear liquids when they are

    Ethyl acetate (systematically‚ ethyl ethanoate‚ commonly abbreviated EtOAc or EA) is the organic compound with the formula CH3COOCH2CH3. This colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues‚ nail polish removers‚ and cigarettes (see list of additives in cigarettes). Ethyl acetate is the ester of ethanol and acetic acid; it is manufactured on a large scale for use as a solvent. The combined annual production in 1985 of Japan‚ North America‚ and Europe
