Introduction The discovery of ferrocene in the 1950s was a doorway to the area of organometallic chemistry and this occurrence was followed by the synthesis of massive organometallic complexes. Although the discovery was unexpected, the impact was enormous. These complexes were extensively used as industrial homogenous catalysts and also in organic synthesis where they supplied…
ABSTRACT The synthesis of cyclohexene from cyclohexanol is an example of elimination reaction. Cyclohexanol, a secondary unsaturated alcohol, undergoes dehydration reaction to form a good leaving group which is H20 because the OH group of an alcohol is a very strong base making it a poor leaving group. The reaction will then be followed by…
Synopsis The objective of this experiment is to enable us to conduct the synthesis of aspirin, reinforce the skills of recrystallisation and reinforce the technique of melting point determination. It is carried out to form ester from an acid and an alcohol. The main procedures are preparation of aspirin, recrystallisation of aspirin and lastly determining…
Introduction substitution reaction are also called displacement reactions .These are the reactions in which an atom or a group of atoms attached to a carbon atom in a molecule is replaced by some other atom or group of atoms without any change in the structure of the remaining part of the molecule. The product formed…
INTRODUCTION What if one day you wake up in a bathtub with your organs cut off, and you cannot remember anything. On the other hand, maybe you are on a street, showing a young woman the directions, and the next thing you know is you are in the middle of nowhere, without your belongings or…
Introduction The aim of this experiment is to establish the most suitable solvent required for recrystallising acetanilide, and to exhibit the methods of vacuum filtration and recrystallisation. Experimental Method (for selection of a suitable solvent): Four solvents: dichloromethane, methylated sprits, petroleum ether and water were tested to see how appropriate they were for recrystallising acetanilide….
Introduction The purpose of this experiment was to synthesize methyl nitro benzoate from methyl benzoate, as well as nitroacetanilide from concentrated nitric acid (HNO3), and concentrated sulfuric acid (H2SO4) by using an electrophilic aromatic substitution reaction. The HNO3 and H2SO4 were combined to form a nitrating solution, which was added to a mixture of methyl…
Introduction The task is to alter and record the different temperatures when magnesium ribbon is places hydrochloric acid. Research questions: How will the magnesium ribbon react to the hydrochloric acid? How quickly will the magnesium ribbon react to the hydrochloric acid at different temperatures? Will it be a slower reaction with the ice bath? Will…
Introduction The purpose of this lab was to use the scientific method to identify an unknown solution, based on the reactions (i.e. color changes) of known solutions with indicator solutions. These known solutions contained different types of macromolecules. Each type of macromolecule reacted with at least one indicator solution in a unique way, which allowed…
Introduction The redox reaction in an electrolytic cell is nonspontaneous. Electrical energy is required to induce the electrolysis reaction. An example of an electrolytic cell is shown below, in which molten NaCl is electrolyzed to form liquid sodium and chlorine gas. The sodium ions migrate toward the cathode, where they are reduced to sodium metal….
