(Author’s name) (Professor’s name) (Course details) (Date Abstract The aim of the lab was to separate and analyse analgesic drugs in a drug tablet. The method used to separate the components was Thin Layer Chromatography (TLC) with silica adsorbent as the stationary phase and 0.5% glacial acetic as the mobile phase. In one plate‚ five known samples were used as the reference‚ that is: Aspirin; Caffeine; Ibuprofen; and Salicylamide. Aspirin and Salicylamide were the only samples that fluoresced

In this lab‚ spectrochemical technique was used to determine qualitively the product of a reaction. The purpose was to learn what a SN1 reaction was with combining 2‚5-dimethyl-2‚5-hexanediol and HCl and to learn how to use an infrared spectrum for analyzing the reaction

The goal of this experiment was to synthesize dibenzalacetone by aldol synthesis. The name ’Aldol synthesis’ was taken from the words ’aldehyde and alcohol’. This is because the product of this reaction contains both an aldehyde and alcohol. The carbon-carbon bond-forming reaction is referred to as aldol addition. An aldol condensation yields many species of products if the reactant is more than one. Therefore‚ the aldehyde has to react with itself to yield one product. Procedure: Followed according

dipole. 6 Structure and Properties of Alcohols •Alcohols have an H atom bonded to an O atom‚ making them capable of intermolecular hydrogen bonding. •All of these properties give alcohols much stronger intermolecular forces than alkanes and alkenes. 7 Structure and Properties of Alcohols •Therefore‚ alcohols have higher boiling and melting points than hydrocarbons of comparable size and shape. stronger intermolecular forces higher boiling and melting point 8 Structure and Properties

Preparation of t-Butyl-Chloride March 8 & 15‚ 2012 Theory: Alkyl halides can be synthesized when alcohols react with hydrogen halides. An alkyl halide is a halogen-substituted alkane‚ and a hydrogen halide is a compound consisting of a hydrogen bonded to a halogen (H-X). Alkyl halides are classified as primary‚ secondary‚ or tertiary depending on the number of alkyl substituents directly attached to the carbon bearing the halogen atom. The purpose of this laboratory experiment was to prepare
