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
Report Organic Chemistry Laboratory II ABSTRACT: The purpose of this lab was to separate and purify two unknown compounds, one solid and one liquid, from an ethereal solution using the techniques of chemically active extraction, vacuum filtration, simple distillation, and recrystallization. Then identifying information was compiled about these unknowns by obtaining experimental melting/boiling point ranges, and analyzing IR and proton/carbon NMR spectrums It was determined that the unknown solid’s
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
1211K Lab Report Briana Limage Drawer #D20 Tuesday December 2, 2014 Lab Day and Time: Tuesday 2-5 Unknown # 4224034-DF14 Introduction The purpose of this semester long experiment was to determine an unknown organic acid. An organic acid is an organic compound with acidic properties. A base reacts with acids to form salts. Titrations are used to determine the concentration of unknown substances. The purpose of the KHP experiment was to determine the molarity of NaOH. HCl titrations
Recrystallization and Identification of Unknown Arsalan Kouser Chemistry 2270 Laboratory, Section 18 Instructor: Kyle Fulle October 8, 2014 Abstract In this laboratory project, Compound “E” was identified as N-Phenylsuccinimide. The % yield was 60.5 %. The melting point of both Compound “E” and N-Phenylsuccinimide was 153-154 ⁰C, as verified through experimentation; the official melting point range of N-Phenylsuccinimide is 153-157 ⁰C. The yield of dibromobenzene
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
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
