    Katie Smith April 11‚ 2013 Competitive Nucleophiles Introduction The purpose of this experiment was to compare the nucleophilicities of chloride and bromide ions toward the n-butyl and t-pentyl alcohols. We were able to analyze this by using refractometry to measure the amounts of alkyl chloride and alkyl bromide in each reaction. Experiment Scheme (Procedure A) To begin the experiment‚ we assembled a reflux apparatus in the fume hood with a 100 mL round bottom flask and a condenser

    The Periodic Table The periodic table has been updated all throughout history. Elements have been around us since the beginning of time. Elements‚ such as gold and silver‚ are examples of these elements that have been known for centuries. The periodic table allows us to see the elements in their families so we can understand what properties they have. It also allows us to see the atomic number‚ atomic mass‚ and the symbol of the element. The periodic table is a source of knowledge that is still
