Ethanoate - Study guides, Class notes & Summaries

Unit 4B: Making Nail Vanish Remover Introduction In the manufacture of ethyl ethanoate, there are a few techniques used, one of them being reflux. The principle behind using reflux is that it boils the reactants without losing any product or reactant, especially through vapour or gas. In the reaction there is a round bottom flask containing the reactants and a condenser with a water inlet and output. Due to organic chemicals being inherently unstable, when heated they will evaporate, res...

An organic ester compound, ethyl ethanoate, of acetic acid with ethyl alcohol, it is a colourless solution which is highly volatile, best known in glues and nail polish remover. This chemical is one of the simplest carboxylate esters with the widest range of uses. This compound liquid has a characteristically sweet, pleasant fruity odour. The chemical used for this experiment must be handled with extreme caution as they are highly corrosive and flammable. So, it is important to wear the right th...

OL Lab 9: Building models of organic compounds Learning Objectives: • Build virtual models to learn about the structure of organic compounds • Draw extended structural formulas of organic compounds Compounds that are based on the carbon atom are known as organic compounds. These compounds commonly contain, nitrogen, oxygen, and hydrogen in addition to carbon. Carbon forms a variety of covalent compounds with varied properties. Carbon containing compounds are formed by sharing electrons, c...

Aspirin is a generic term for acetylsalicylic acid. This substance was first introduced in the late 1890s, that has become a ‘’non-steroidal anti-inflammatory drug’’, non-opioid analgesic and antiplatelet drug which is widely used for medicinal purposes. Aspirin will not react against the acetic conditions of the stomach, yet it is hydrolysed in the intestines as it will react on alkaline conditions to create ethanoate ions and salicylate. Aim: In this practical, an Aspirin will be made...

Unit 4: Esters. How can you make simple esters? Heating a mixture of ethanoic acid and ethanol with a few drops of concentrated sulfuric acid produces ethyl ethanoate Ethanoic acid + ethanol -> ethyl ethanoate + water CH3COOH + CH3CH2OH -> CH3COOCH2CH3 + H2O Starting materials: ethanol and ethanoic acid Catalyst: concentrated sulfuric acid Conditions: heat The concentrated sulfuric acid isn't written into the equation because it is a catalyst and therefore isn't consumed in th...

This assignment contains three experiments: -chlorination of 2-methylpropan-2-ol -nitration of methyl benzoate - preparation of an ester (ethyl ethanoate) they contain conclusions and evaluation

Acid-Base Equilibria Bronsted-Lowry theory of an acid? - correct answer An acid is a substance which can donate a proton (H+) to a base. Bronsted-Lowry theory of a base? - correct answer A base is a substance which can accept a proton (H+) from an acid. (N.B. All bases must have at least one pair of electrons to be able to accept a proton. T/F: When an acid loses a proton to a base, it forms a base itself. - correct answer True. Similarly, when a base accepts a proton from an acid, it for...
