The solvent used is a 3:1 mixture of toluene and petroleum. After the developing chamber is prepared‚ it is essential to begin preparation of the unknown DNPH derivative[6]. The preparation of the 1‚2 DNPH derivative of a ketone is in fact a small organic synthesis which produces a fraction of a gram of product. The second part of the lab makes use of NMR Spectrometry. NMR takes advantage of the magnetic properties of the 1H & 13C nuclei. We are only concerned with 13C because 12C does not have

CLASSIFICATION TESTS A. Acids There are relatively few suitable tests for carboxylic acids. Classification is based mostly upon solubility tests. If the compound is water soluble‚ test the aqueous solution of your compound with pH paper (also check the pH of the original water). If the compound is water-insoluble and it dissolves in 5% (1.5M) sodium hydroxide and 5% NaHCO3 solutions as performed in your solubility tests‚ it can be classified as a carboxylic acid. Establish an equivalence value

impurities have on the melting point of an organic compound? Soluble impurities affect the melting point of a solid in the following manner. a. The presence of an impurity in the molten compound reduces its vapor pressure thus lowering the melting point of the compound. b. Broaden the melting point range. 2. For what tow purpose are melting points routinely used a. To determine the identity of an organic solid. b. To determine the purity of an organic solid. 3. What effects on the measured melting
