Solubility and Functional Groups _______________________________________________________ You will recall from general chemistry that a solution has two components: the solvent‚ which is the substance present in greater amount‚ and the solute‚ which is dissolved in the solvent. Solubility is defined as the mass (in grams) of solute dissolved in 100 g of solute at saturation. Molar solubility is defined as the amount (in moles) of solute per liter of saturated solution. The solubility of one compound

Although it is classified as a weak acid‚ concentrated acetic acid is corrosive and attacks the skin. Source: http://en.wikipedia.org/wiki/Acetic_acid Octanol The term Octanol usually refers to the isomer‚ octan-1-ol‚ with the molecular formula CH3(CH2)7OH. It is a fatty alcohol. Many other isomers are also known. Esters of octanol‚ such as octyl acetate‚ occur as components of essential oils. Octanol is manufactured for the synthesis of esters for use inperfumes and flavorings. It is used to evaluate

Synthesis of Isopentyl Acetate (Banana Oil) Using A Fischer Esterification Reaction Purpose: The purpose of this experiment is to synthesize Isopentyl Acetate using a Fischer esterification reaction. Fischer esterification is an acid-catalyzed condensation of an alcohol and a carboxylic acid‚ yielding an ester and water. Isopentyl Acetate has the scent of banana oil‚ once synthesized it will be purified by distillation. Then the analysis of the sample using H NMR and IR will determine purity

Chris CXXXX Organic Chemistry Lab Dr. Lyn XXXX 2 February 2012 Esterification of Isopentyl Alcohol to Isopentyl Acetate Procedure The technique for esterification that was employed in the experiment was to use a reflux apparatus (Figure 1) while heating in order to evaporate out water to drive our reaction into the product favored direction. The starting material of isopentyl alcohol (1.0 mL) and excess glacial acetic acid(1.5 mL‚ 17.6M) were eppendorf pipetted into a 5 mL conical vile. This
