Preparation and SN1 Reactivity of 2-Bromobutane Whitney Bellido Department of Chemistry‚ Illinois State University‚ Normal‚ IL 61790-4160 Submitted: April 4th‚ 2013 Introduction The overall goal of this experiment is to understand and be familiar of SN1 reactivity. We also learned how to prepare 2-Bromobutane by learning how to distill and extract this product from its organic layer. Finally‚ another goal was to specifically understand the relative reactivity of alkyl halides under SN1 conditions

oxidation (loses electrons and hydrogen‚ gains oxygen) ‚ where the negative electrode (cathode) experiences reduction (gains electrons and hydrogen‚ loses oxygen). In our daily lives‚ we can see the applications of electrolysis in many ways. The process of electrolysis is used for accumulators (car batteries)‚ electroplating (the covering of another metal surface with another metal)‚ and the manufacturing of many kinds of chemicals such as chlorine‚ sodium chloride‚ and bleach. Also‚ electrolysis

the ore Bauxite) is used For Group 1 and 2 metals‚ the metal chlorides are usually used. Electrolysis is a very expensive process because of the cost of electrical energy. Carbon Zinc Iron Lead Zn Fe Pb Reduction of the metal oxides in a blast furnace. Carbon is used as the reducing agent. It is often in the form of coke (made from coal). Although this uses a lot of energy‚ this is cheaper than using electricity. Hydrogen Copper Silver Gold Cu Ag Au These metals occur “native”
