Preparation of 1-bromobutane? | Yahoo Answers

Preparation of 1-bromobutane? | Yahoo Answers – Hi something unusual on my lab report asking "In your lab report identify the major differences between the two IR spectra. What groups on the 1-butanol or 1-bromobutane give rise to the major signals/differences?" This is the link to the IR Spectra: bit.ly/1lSTDeA Please if you can help me with as much explanation as possible. Thanks a tonne!Che 317 Lab Report Title: Synthesis of 1-Bromobutane Name: Date: Mcle af Bernuudane Balanced Reaction Equation: 6.19 Table of Physical Constants Compound NaBr CH3(CH2)2 CH2OH М.AW. 102.9 density bp/mn www 118 102 74.1 0.810 1.275 CHs(CH2)2CH2Br 137.0 CH (CH2) CH2B СН3{CH-):СH-ОН NaBr 132- MW 24.1 Oll mut 412 L02.4 0.17m Moles G.OY90 17 grams NA density 10 mL Na S.LGML Results: Calculatehave easily co-distilled along with water and 1-bromobutane after refluxing, as a consequence of this 1-bromobutane must be extracted by work-up with water in order to dissolve as much 1-butanol as possible, following this is the addition of cold (to avoid charring of organic layer) sulfuric acid and sodium hydroxide (removes sulfuric acid that

The purpose of this experiment is to determine the concentration of an unknown copper(II) solution by spectrophometric analysis. Introduction. THE PREPARATION OF 1-BROMOBUTANE FROM 1- BUTANOL;The purpose of this experiment is to synthesize 1-bromobutane from 1-butanol and sodium bromide. In order for this reaction to reach completion there are four major operations that need to be performed. The four major operations include refluxing, simple distillation, separation, and drying.Lab Report Title: Synthesis of 1-Bromobutane Name: Date: Equation: Table of Physical Constants Compound M.W. density bp/mp NaBr 102.9 —– — CH 3 (CH 2) 2 CH 2 OH 74.1 0.810 118 CH 3 (CH 2) 2 CH 2 Br 137.0 1.275 102 CH3(CH 2) 2 CH 2

Synthesis Of 1-bromobutane From 1-butanol [546gywvqmqn8] – NUCLEOPHILIC ALIPHATIC SUBSTITUTION: SYNTHESIS OF 1- BROMOBUTANE OBJECTIVES: To synthesize 1-bromobutane through a nucleophilic aliphatic substitution. To understand the use of distillation and extraction in the context of the synthesis. To characterize the desired product with GC-MS. Background A substitution reaction occurs when a suitable substrate undergoes a substitution by a nucleophile.The conversion of 1-butanol to 1-bromobutane relies on sulfuric acid which plays two important roles. First, it protonates the alcohol of 1-butanol to form an oxonium ion which is a good leaving group. Secondly, it produces the hydrobromic acid, the nucleophile, which attacks 1-butanol causing the oxonium ion to leave and forming 1-bromobutane.Global reaction for the synthesis of 1-bromobutane. This halide is easily prepared by reacting butan-1-ol (primary alcohol) with sodium bromide solution and excess of concentrated sulfuric acid. The reaction between sodium bromide and sulphuric acid origins hydrobromic acid (Equation 1).
