The goal of the project was to characterize an "unknown" organic acid in order to make a proper identification of the acid, while learning proper techniques for scientific measurement and analysis of error. In order to ensure the most accurate data, a purification was performed by the process of recrystallization. To perform the recrystallization the powder was dissolved in a minimal amount of hot ethanol/H2O solvent that allowed the unknown powder to crystallize properly when cooled. This process
accomplish the task? What techniques were used to purify and identify the product(s) of the reaction? In this experiment, an acid-base extraction was done to separate a mixture of an unknown acid and fluorene, a neutral compound. The possible unknown acids were 2-chlorobenzoic acid, 3-chlorobenzoic acid, and 3-methylbenzoic acid. The purification of the isolated unknown acid was performed by recrystallization and its identity was established by analyzing the melting point range of the pure product
experiment, a Fischer Esterification reaction was performed with two unknown compounds. The unknown compounds, Acid 2 and Alcohol D, were identified by using the knowledge of the reaction that took place, and the identity of the product that was synthesized. The identification of the product resulted from analysis of IR and NMR spectra. For this experiment, Alcohol D and Acid 2 reacted in the presence of concentrated sulfuric acid, resulting in a colorless solution with brown layer on top. After washes
REACTIONS: IDENTIFICATION OF AN UNKNOWN BROMIDE (Preparative) Introduction The first purpose of the lab was to prepare an unknown organomagnesium bromide, an organometallic reagent, reacting an unknown aryl bromide with magnesium in anhydrous ether. The unknown was chosen from a predetermined list of benzoic acid derivatives with varying molecular weights and melting points (see Supplement C). The second purpose of this lab was to prepare an unknown carboxylic acid by reacting the unknown aryl-magnesium
Organic chemistry 201 | Mixed Melting Points | Determination of an Unknown Solid | | [Type the author name] | 9/15/2011 | Purpose : The main purpose of this experiment was to identify an unknown compound/substance by performing multiple experimental melting point tests. Pure and impure solids were tested to see what affect pureness/impureness had on a melting point. Background: The melting point of a solid can be used to determine the purity of the solid. Pure samples usually have
Identification of Unknown Organic Compound by Melting Point (M.P), Boiling Point (B.P) and Infrared Spectroscopy Methods and Background The main objective of this lab is to identify the given unknown organic compounds with various methods. Identification of an unknown compound is important to perform through the process of melting point (M.P), boiling point (B.P) and Infrared spectroscopy (I.R). Index of Hydrogen deficiency (IHD) and elemental analysis makes an experiment more efficient in
Infrared Spectroscopy Organic Chemistry Lab 301A B. The purpose of this lab is to study Infrared Spectroscopy, which focuses on the study of the electromagnetic spectrum. The area to be studied is the infrared region, which is made up of gamma, X, and UV rays. We want to be able to identify spectra’s to their complementary structures. The background of this experiment particularly deals with the study of compound structure determination, and traits. We must be aware of the functional groups

Nitration of Methyl Benzoate Abstract: This procedure demonstrates the nitration of methyl benzoate to prepare methyl m-nitrobenzoate. Methyl benzoate was treated with concentrated Nitric and Sulfuric acid to yield methyl m-nitrobenzoate. The product was then isolated and recrystallized using methanol. This reaction is an example of an electrophilic aromatic substitution reaction, in which the nitro group replaces a proton of the aromatic ring. Following recrystallization, melting point and infrared
the clove oil extract by using GCMS Introduction Essential oil components of clove are the volatile plus the ethereal liquids that have had a long history of utilization. These essential oils and the ethereal compounds are normally extracted from organic compounds. The clove oils are in many cases extracted from plants extracts. Methods of oil compound extraction are dependent on the plant type used in extraction. Some of these extraction methods used in clove oil components include method of distillation
