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

turned blue - Postlab Questions 1. Whas is the theoretical yield of casein based on the table of Milk Composition Analysis? 3.3 % 2. What is your percent yield? 3.2g/3.9g x 100= 82% 3. Why might your percent yield be lower than expected? More fat has a decrease in protein which would cause a lower percent yield. 4. Why might your percent yield be higher than expected? Less fat causes an increase in protein‚ thus giving a higher percent yield. 5. In the precipitation of casein‚ why is it important

Temperature: (122.2+126.1)/2 = 124.15 °C Average MP Range: 120.75 - 124.15 °C Actual MP of Benzoic Acid: 122.4 °C (Fisher Scientific MSDS #02720: Benzoic Acid) Discussion: The results of the experiment show a percent yield of 34.34% for the first trial (Part A)‚ and a percent yield of 84.0% for the second trial (Part B). The methods for both trials were generally the same‚ so the large difference is attributed to the fact that the beaker broke before the gravity-filtering step in the first trial

Title: Preparation of Cyclohexene from Cyclohexanol Aim: To prepare an alkene‚ cyclohexene‚ by the dehydration of an alcohol‚ cyclohexanol‚ and better understand the processes that take place during this reaction. Introduction: One of the common ways of preparing an alkene is through the dehydration of an alcohol. In this experiment cyclohexanol is dehydrated to prepare cyclohexene while using sulfuric acid as a catalyst. A bromine test can be later done to ensure that the end product is
