This lab will help guide you in the direction to predict the regioselectivity and activation vs. deactivating powers of the nitro-group. Gas Chromatography will be used to analyze compounds that can be vaporized without being decomposed. GC is also used to check the purity of a substance‚ and separating the

Nitration of Naphthalene Wed 2/25/2015 Lab report # 1 Abstract: The purpose of this experiment was to nitrate naphthalene with nitronium ion‚ which is formed at low concentration from a reaction of nitric acid and sulfuric acid. The percent yield from the experiment was 54.4% of the product‚ and the melting point of the possible results were 59 °C for 1-nitronaphthalene‚ and 78°C for 2-nitronaphthalene. Introduction: Polynuclear aromatic hydrocarbons such as naphthalene can be nitrated

not. Not many fruits and vegetables contain preservatives simply because they come from nature. One of the items contained Sodium Benzoate‚ a small percentage of people are extremely sensitive to sodium benzoate and can experience asthmatic attacks and other allergic reactions when they take in the preservative. A more normal problem is the combination of sodium benzoate and citric acid and ascorbic acid. When these ingredients mix‚ they form benzene‚ a cancer-causing chemical linked with leukemia

We performed two procedures in which we reduced methyl acetoacetate. For the first procedure we produced a racemic mixture of Methyl (S)-3-Hydroxyacetate and Methyl (R)-3-Hydroxyacetate. For the second we produced only one of the enantiomer products depending on which enantiomer of Tartaric Acid was used. A reduction is a reaction which generally means adding more carbon-hydrogen bonds to a compound. In a reduction reaction the oxidation number of a carbon atom decreases. The opposite is an oxidation
