sodium hydroxide (0.4g‚ 0.01 mol)‚ distilled water (2 ml) and ethanol (2ml‚ 95%) were mixed into a clear solution. The solution was then cooled to room temperature. Benzaldehyde (0.8ml; 9.82g‚ 0.008mol) was then added to the solution followed by addition of acetone (0.3ml; 0.24g‚ 0.004mol) and formed into a thick yellow solution. The flask was then swirled gently and constantly for 5 minutes. This turned into a fluffy precipitate as the flask was swirled. After 5 minutes of constant swirling‚ the

Title : Properties of hydrocarbon Objective : 1) To study the properties of hydrocarbons. 2) To determine the unknown samples. Results : Part A : Combustion Compounds Observations Hexane There was orange flame and burned mildly during the burning process. No soots and smoke were produced. C6H14 + 19/2 O2 6CO2 + 7H2O Cyclohexene Orange flame burned vigorously. A small amount of black soot and smoke were produced during the burning process.

Multistep Synthesis of Tetraphenylcyclopentadienone Author: Instructor: Date work performed: 10.18.2012--10.25.2012 Date work submitted: 11.01.2012 Abstract: The aim of this experiment was to perform a multistep synthesis to form tetraphenylcyclopentadienone. The first step of the reactions was to synthesize benzoin from the condensation of benzaldehyde. A yield of 28.91% benzoin was obtained. The MP of benzoin was 127O-130O C and the IR spectra displayed a carbonyl peak at 3415 cm-1

The E2 reaction performed began by dehydrohalogenating the 3-chloro-3‚ 7-dimethyloctane with potassium hydroxide in aqueous ethanol. The 3-chloro-3‚ 7-dimethyloctane will lose a hydrogen from three different carbons that cause the formation of three constitutional isomers. If the hydroxide ion attacks a hydrogen on the 3-methyl carbon‚ then 2-ethyl-6-methyl-1-heptene will be the product. If a hydrogen on the carbon-2 was attacked‚ then the product would be 3‚ 7-dimethyl-2-octene. If a hydrogen was

produce other functional groups (e.g.‚ amines‚ esters‚ and alkenes). Alkyl halides have the general formula RX (where R= alkyl/substituted alkyl group and X = F‚ Cl‚ Br‚ or I.) They are insoluble in water and sulfuric acid and are soluble in organic solvents.[3] They are synthesized for their many uses. There are several ways by which alkyl halides can be synthesized. Some of those are halogenation of alkanes with Cl2 or Br2‚ addition of HX to

Nate Rhodes The Synthesis of Alkenes: Dehydration of Cyclohexanol Organic Chemistry Lab 1 Tuesday 8:00 11/08/11 Paul Jackson Abstract: The goal of this experiment was to form cyclohexene from cyclohexanol through a dehydration reaction. Cyclohexene was successfully synthesized according to the bromine test performed and the IR spectra. There was a percent yield of cyclohexene of 76.1%. Introduction: Alkenes‚ hydrocarbons containing at least one carbon-carbon double bond‚ are important

Esmeralda Curiel Organic Chemistry October 21‚ 2014 Experiment 41- 1‚4-Diphenyl-1‚3-Butadiene INTRODUCTION The study of the Wittig Reaction is important because it is often used to form alkenes from carbonyl compounds. The purpose of this experiment is to isolate the trans‚ trans-1‚4-diphenyl-1‚3-butadiene‚ which is formed by a Wittig reaction along with the cis‚ trans isomeric diene. The reaction is carried out in two steps. First the Wittig salt is obtained through a simple nucleophilic displacement

TLC plate 1 was taken after adding the initial addition of 0.25mL of bleach. TLC plate 2 was taken after adding an additional 0.08mL of bleach because plate 1 still showed presence of SM in the CP lane. TLC plate 3 was taken after adding an additional 1mL of bleach for the same reason. However‚ TLC plate
