Document Summary
You must type directly into the answer boxes of the report template. Font or size-altered answer boxes will receive a mark of zero. Structures may be written by hand in pen. Explain how liquid-liquid extraction can be used to separate different organic molecules. (1 mark) Explain the difference between extracting the organic layer and washing the organic layer. (1 mark) Illustrate the mechanism (using arrows to show the flow of electrons) for the reaction that occurs between naoh and a general carboxylic acid (r-cooh). State which layer (organic or aqueous) that each individual species (reactants and products) is in. (1 mark) Illustrate the mechanism (using arrows to show the flow of electrons) for the reaction that occurs between hcl and the sodium salt of a carboxylic acid (r-coo . State which layer (organic or aqueous) that each individual species (reactants. 266l fall 2015 and products) is in. (1 mark)
