Investigative question: how are esters formed ? Esters are formed by the reaction of an alcohol and a carboxylic acid‚ usually in the presence of sulphuric acid to catalyse the process‚ or by the reaction of an acyl chloride with a carboxylic acid (this requires no catalyst and is irreversible without additional reactants) are the most common ways used. Others include reactions of certain molecules such as structural rearrangement. Apparatus: Plastic dropping pipettes‚ Beaker (100 cm3 or 250

Question 1 In chapter four of Refounding Public Administration‚ Gary L. Wamsley argues that public administration and public administrators are now facing new challenges that threaten the very core of democracy in today’s society.

Title: Experiment 28: Nitration of Methyl Benzoate Objective: The students will learn to nitrate methyl benzoate through electrophilic aromatic substitution reaction. They will learn the importance of regiochemistry in chemical reactions. They might experience disubstitution through a high temperature. Reactions: Observation: The crystals started to form when added 2 g of crushed ice. The addition of hot methanol dissociated the crystals. The crystals reappeared when cooled down in

Preparation and isolation of an Ester Aim: To make an ester and purify it Background Theory: Esters are derived from carboxylic acids and alcohols with the presence of a catalyst. A carboxylic acid contains the -COOH group‚ and in an ester the hydrogen in this group is replaced by a hydrocarbon group of some kind. Sulfuric acid (H2SO4)is used as a catalyst for this reaction in order to accelerate the rate at which the product is formed. The general formula of an ester is RCOOR’ in which R is the

On the stage of philosophy concerning meta-ethics‚ the Moral Error Theory followed in Hume’s footsteps and made significant breakthroughs with J. L. Mackie’s Ethics: Inventing Right and Wrong and Richard Joyce’s more recent The Myth of Morality. They both argue that i) moral judgments presuppose objective and categorical moral values and ii) this presupposition is false since there are no such things. Therefore‚ they conclude‚ moral judgments are systematically false. Although Mackie offers an argument
