Hydrogen bonding in the trichloromethane-ethyl ethanoate system Aim: Trichloromethane and ethyl ethanoate, do not form hydrogen bonds with themselves but they do with each other. In the practical, we shall investigate the formation of hydrogen bonds when the two liquids are mixed. Hypothesis: The more Trichloromethane that we add to ethyl ethanoate and the more ethyl ethanoate that we add to Trichloromethane the higher the boiling point of both solutions. Apparatus: * Reflux apparatus * 0-100°C thermometer * Measuring cylinder of 10 cm3 * Measuring cylinder of 25 cm3 * Trichloromethane * Ethyl ethanoate Method: The first part of the practical is to record the boiling pint of trichloromethane and ethyl ethanoate.> Then set up the reflux apparatus fitted with a thermometer as show in fig. 1.> Put 10 cm3 of ethyl ethanoate in the flask and warm very gently until steady boiling and refluxing occurs.> Note the temperature.> Move away the Bunsen burner and allow the apparatus to...
