Unformatted text preview: Madison McVey CHEM 237 549 December 5 2016 Dehydration of Cyclohexanol Lab Report In this lab students were expected to form cyclohexene through the dehydration of cyclohexanol in an elimination reaction The conical vial was weighed before the reaction took place and was found to weigh 19 730 g After the reaction the vial weighed 20 317 g thus yielding … 1. 2. The general approach towards carrying out an organic reaction: (1) Write out the balanced reaction, using structural formulas. Annie Lu & Minh Nguyen CHEM 251 - Dr. Joe 1) Complete mechanism for the reaction: E1 reaction: SN1 reaction: 2) 5mL cyclohexanol = 4.81g cyclohexanol (Dcyclohexanol = 0.962 g/mL) % yield = Actual mass = Theoretical yield. Brooklyn College. Experiment 11: Dehydration of Cyclohexanol INTRODUCTION In this experiment, cyclohexanol is dehydrated by aqueous sulfuric acid to produce cyclohexene as the sole product [equation (1)], and no rearrangement is possible in this reaction. Dehydration Of Cyclohexanol Lab Report – A lab report is basically how you describe what you’ve carried out in a lab experiment, what you found, and the outcomes. dehydration cyclohexanol chm3003 laboratory sadaf afif may 07, 2018. lab partner: khoe abstract: in this lab, cyclohexene is prepared by dehydrating. Orgo Lab Preview text Melina Rosado Rosales Chemistry 2612 Organic Chemistry Lab Lab Report #8 Dehydration of Cyclohexanol 04-17-17 Introduction The purpose of this experiment is to dehydrate Cyclohexanol via E1 reaction mechanism to form Cyclohexene. View Organic Chemistry I Lab Report 6.docx from CHEM 1073 at University of Texas, San Antonio. Cool the mixture to room temperature, and add a few boiling chips to the cooled solution. See the last page of this handout for more information. Your first formal report will be for this experiment. Outline mechanism for the dehydration of 1-methyl-1-cyclohexanol. 3. In the experiment, the lab manual dictated 8.0 g of solid cyclohexanol was to be used, but since the lab had only the liquid form, the amount to be used was calculated using density. DEHYDRATION OF CYCLOHEXANOL Lab Report 1. YIELD (Hand in the sample with the report, show calculations on back of this sheet) Limiting Reagent Moles Used Product Molecular Formula Mole Wt (-7 Theoretical Yield (moles) 24 Actual Yield (grams) Actual Yield (móles) Percent Yield 。 See the last page of this handout for more information. Provided that the initial mass of cyclohexanol was 9.84 g while the final product of cyclohexene was only 2.43 g, the 30.1% yield is expected. Synthesis of Cyclohexene The Dehydration of Cyclohexanol. What is the major disadvantage of using concentrated sulfuric acid (or hydrochloric acid) rather than 85% phosphoric acid for the dehydration of alcohols? Cool the mixture to room temperature, and add a few boiling chips to the cooled solution. OVERALL REACTION 2. Dehydration of an alcohol is an elimination reaction based on states of equilibrium; therefore, the yield of the final products will never be 100%. In this lesson, we will focus on the dehydration reaction that cyclohexanol undergoes under acidic conditions to produce cyclohexene, a useful building block in organic chemistry. Due after completing the lab. Synthesis of Cyclohexene via Dehydration of Cyclohexanol . MECHANISM 3. Cyclohexane and the lab report for this course. University. Dehydration of Cyclohexanol – Preparation of an Alkene CHM 220 PROCEDURE: (take care to record any necessary data for your lab report) 1) To a 50mL round bottom flask add 10mL of water and then slowly add 10mL of concentrated sulfuric acid. The. Your first formal report will be for this experiment. Dehydration of Cyclohexanol – Preparation of an Alkene CHM 220 PROCEDURE: (take care to record any necessary data for your lab report) 1) To a 50mL round bottom flask add 10mL of water and then slowly add 10mL of concentrated sulfuric acid. density of cyclohexanol is 0.962 g/mL. The general approach towards carrying out an organic reaction: (1) Write out the balanced reaction, using structural formulas. Synthesis of Cyclohexene via Dehydration of Cyclohexanol . 1.2216 g 100 =30.97 4.81 g 82.143 g /mol 100.158 g /mol By using this equation: 0.962 g 8.0 g = 1mL x mL, the total. Lab Report Fundamentals is extremely important to any trainee who’s operating in… (2) Construct a table of relevant information for reactants and products – e.g., MPs, BPs, MWs, densities, hazardous properties. Sign in Register; Hide. amount that was used was 8.32 mL. The general approach towards carrying out an organic reaction: (1) Write out the balanced reaction, using structural formulas.
