Lidia Santiana Palha s3333523 Experiment 2: Williamson Ether Synthesis of 2-octadecyloxynaphthalene Demonstrator: P. Kabauri Date of experiment: 26-09-2017 Summary: In this experiment, 2-octadecylooxnapthalene was synthesized. The synthesis consists of making 2-naphthol solution with acetonitrile. Then CsCO3 and bromooctadecane was added to the solution. And at the end we crystalized it and found out the melting point which ranged from 64-68°C. Theory: In order for an ether to be produced we needed an aroxide ion and an alkyl halide. The reason why we use acetonitrile is because it acts as a solvent and ions can form in it. CsCO3 when added into acetonitrile it forms Cs+ ions and carbonate ions. Also the acetonitrile does not react in the reaction and hence does not interfere with the reaction. …show more content…

The 2-naphthol is very acidic, and therefore can function as an acid, and in the presence of a strong base, CsCO3 ,(See diagram below), the lone pairs of electrons on the oxygen in CsCO3, is going to take the proton from 2-napthol (O-H), and the electrons from the proton are going to move into the oxygen. Then we will have 3 lone pairs of electrons on the oxygen of 2-napthol giving it a -1 charge and hence aroxide ion is
