Williamson Ether Synthesis of Nerolin

Name: Naira Raquel Xilau TA: Elizabeth Hirst catch: 11/12/2012 williamson divinyl ethyl ether synthesis of nerolin In this experiment, it was performed the williamson ether synthesis of nerolin. Williamson ether answers be receptions where an alkoxide reacts with a primary haloalkane or a suffonate ester. The reaction occurs through a SN2 mechanism. SN2 reactions atomic number 18 characterized by the inversion of stereochemistry at the site of the leaving assembly. Because the reaction is set in motion by the arsehole attack of the nucleophile, the nucleophile and the electrophile are in anti-configuration (chemwiki.org). Nerolin is part of a congregation of alkyl aryl ethers, compounds vastly take in in the produceion of odours- close specifically as perfume additives and scent fixatives. These scents include rose, lilac and lemon (prelab-notes).

Given the stoichiometry of the reaction being 1:1, 2-naphthol was make to be the limiting reagent. Since the percentage yield was not genuinely high, it is plausible to assume that roughly errors may occurred that contributed for the lower yield. Those errors may be caused by the neither dryness of the product, loss of product during decline and wrong add together of reagents. If the experiment was to be repeated, to a greater extent share would be incumbent especially during extraction and evaluate of the reactants, in...If you indispensability to get a full essay, order it on our website: Ordercustompaper.com
