were liquid‚ oily‚ and it had a banana smell. Introduction Artificial flavoring is commonly used in the food that we eat today. For example‚ fruit flavoring is a chemical mixture that mimics a natural flavor as that of banana flavor from the synthesis of isoamyl acetate. Ester is the functional group‚ which is responsible for the distinctive odor and taste that artificial fruit flavoring has. Esters are derived from carboxylic acids. A carboxylic acid contains the –COOH group‚ and in an ester

Synthesis of Isopentyl Acetate Abstract The purpose of this experiment was to produce isopentyl acetate‚ banana oil. Acetic acid and isoamyl alcohol were used to synthesize isopentyl acetate. The techniques used for the separation and purification of isopentyl acetate were reflux‚ liquid-liquid extraction‚ neutralization and distillation. The identification of isopentyl acetate was based on boiling points and an infrared spectrum. This experiment resulted in a 11.68% yield. The reactants

SYNTHESIS AND CHEMISTRY OF K2S2O8 ABSTRACT In this experiment‚ a sample of K2S2O8 was prepared by the electrolysis of an aqueous solution of H2SO4 and K2SO4. The peroxodisulfate anion‚ S2O82-‚ was also observed for its ability to serve as a counterion for precipitation by preparing a copper (II) complex by reacting hydrated copper (II) sulfate with ammonium peroxodisulfate in the presence of pyridine. This same ability‚ coupled with its strong oxidizing ability allowed for stabilization of

Introduction Discussions of any sort are supposed to help us develop a better perspective on issues by bringing out diverse view points. Whenever we exchange differing views on an issue‚we get a clearer picture of the problem and are able to understand it. The understanding makes us better equipped to deal with the problem.This is precisely the main purpose of a discussion. The dictionary meaning of the word Group Discussion is to talk about a subject in detail. So‚group discussion may refer to a

Protein Synthesis Notes If DNA’s shape is altered it can’t function properly. RNA is more flexible so changing the shape changes the function‚ which is wanted. Any shape of RNA can become another. Three shapes/functions of RNA: -mRNA: messenger (linear_____) -rRNA: ribosomal (large and like a globe) More stable than mRNA. -tRNA: transfer (shaped like t) If you flatten this it becomes mRNA.
