Cyclohexene Lab Report

720 Words3 Pages

This experiment converted cyclohexanol into cyclohexene by means of elimination reaction with the addition of 85% phosphoric acid. In comparison, the product obtained was a clear colorless liquid with a strong odor similar to the original solution. However, when combined together in the seperatory funnel there was two distinct layers formed. This is evident that a reaction took place and the product formed is a different compound than the original. In order to confirm that a different product was formed, additional test were performed to solidify the characterization. Test such as Bromination, IR spectroscopy, refractive index, and measures physical properties confirmed that the product collected was the desired product, cyclohexene. A bromination …show more content…

The refractive index literature value according to the Merck index for cyclohexene is 1.4465 while cyclohexanol is 1.465. Comparatively, the difference between the obtained and literature value for cyclohexene is 0.0005. While, the difference between the product and literature value for cyclohexanol is is 0.018. Although, the Merck Index values of the two compounds are relatively close, the product obtained is considerably closer to the cyclohexene value. Ultimately, the refractive index supports that the product obtained is the desired product …show more content…

The boiling point measured was 86ºC in comparison to the literature boiling point for the desired product, cyclohexene, at 83ºC. The starting materials, cyclohexanol, boiling point was listed as 161ºC. This value is too high for the measured boiling point for the product obtained. As a disclaimer, the thermometers used in lab are alcohol based that result in the skewed boiling point measurements in comparison to the actual literature values. In short, the obtained products boiling point measured was similar enough to the desired product to conclude that the product obtained is indeed the

The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.

As mentioned in number 13, the data for the melting point makes sense because my pure product and given compound almost perfectly matched. 17. Again as explained in number 14, the TLC data made sense because my pure compound and 4-tert-butylbenzyl phenol had similar distances from the solvent origin of the plate. The presence of benzyl bromide and benzyl alcohol also explains how not all the product dissolved in the filtrate.

Dehydration Of 2-Methylcyclohexanol Lab Report

967 Words | 4 Pages

The dehydration of 2-methylcyclohexanol takes place at the bottom of the Hickman still. As the Hickman still heats up within the sand bath, the products evaporate and travel higher up in the still where they condense into a liquid and fall within the collection ring, thus separating the product from the remaining water. Drierite (CaSO4) is also added as a drying agent to absorb any leftover water within the product. The purity of the product will then be analyzed with infrared spectroscopy, paying attention to OH peak if it is present. Chemical Reactions: Data and Observations: Material Volume Mol.

Configurational Isomers In Butane

1725 Words | 7 Pages

Stereoisomers Stereoisomers are isomeric molecules that have same molecular formula and sequence of bonded atoms, but differ in the arrangement of the atoms in space. The consideration of such spatial aspects of molecular structure is known as stereochemistry. Stereoisomers can be classified into two general categories: • Conformational isomers Isomers that differ in relative position of some of the atoms in the molecule in 3D-space due to the rotation about formally single bonds (sigma bonds). • Configurational isomers Isomers that arise due to some kind of rigidity in the molecule and they can be interconverted only by bond breaking or making.

This was proved by utilizing the IR spectrum to verify the C =O was not in the final product as it lacked the 1640 cm-1 peak. The melting point of 113-115 degrees C proved that the final product obtained was the E-Stilbene. The TLC plate proved that the E and the Z product was produced, show cased by the double intensity of the DCM spot to the final product’s spot, both which had an Rf of 0.92. The double intensity proved that both products were produced, but through heating and filtering, the Z-Stilbene was

However, the yield of methyl benzoate was likely lower than the calculated 47.40% since a majority of the product was diethyl ether solvent. As noted in the GC analysis, over 90% of the product was diethyl ether according to the peak areas. Due to an external situation, the solvent was evaporated by heating the product on the hot plate. This was less effective than the preferred method of blowing air over the top of the

Isomers Lab Report Essay

This melting point data confirms that isomerization occurred, since the melting point of dimethyl maleate is only -17℃, while the melting point of dimethyl fumarate is 102-105℃. This also highlights the fact that diastereomers have different chemical properties, such as melting point. Since the experimental melting point range almost overlaps with the expected range, there is little error in this measurement. The small amount of error could have occurred from the MelTemp temperature rising too quickly, leading to errors when reading the

Hexane Lab Report

Solvent used in the elution process would be the mobile phase and solvents of different polarity would have a significant impact on the separation due to the varying solubility of compounds in different solvents. Hexane, being the less polar solvent, interacts mainly with the less polar analytes but very slowly with polar analytes. Therefore using hexane at the start of the elution process allows the less polar compound to be eluted out first. After the complete collection of less polar analyte, the mobile phase was changed to the more polar hexane/ethyl acetate solvent, which has stronger interaction with the more polar component, allowing it to be eluted out faster. The change in solvents throughout the elution process would allow for an effective and efficient separation of the compounds β-carotene and chlorophyll in the crude extract of green leaves.

Hydrogen Chloride Lab Report

Hydrogen chloride has a very powerful smell. It is in the form of a gas but only when it is at room temperature which is approximately 25 Celsius and when the pressure is high. When you add water to hydrogen chloride then it breaks down into small pieces which are known as dissolving. The solubility of hydrogen chloride is very high this means that it can dissolve in water quickly because it dissolves many times in its own solution (the gas form of hydrogen chloride). It is very soluble because the smaller the chain of the molecules are then the energy will be required in small quantities however if the chain is long then it will need more energy
