Assignment #1

Working in chemical engineering field, I believe most of the time will need and require a lot of writing report, which required for the writer on being professional including when they write a report on their research. By knowing this, I believe this class is good start to learn on how to make a good professional writing report. Which this learning will be really useful for me in the future if my job requires me to work and write a writing report on the research or job I am working on.
First for the basic things I need to know to complete the first Assignment is ‘what is the purpose of the first assignment?’ Which is to learn the format on writing a paper, how to research to answer all the tasks using provided

In Table 3, the boiling point and enthalpy of vaporization are increasing as the number of carbon and hydrogen are increasing. If we make analysis on all three of the tables, alkanes have the lowest boiling points, then follow by straight chain 1-alcohol, then 1-monochlorinated alkanes. As for the enthalpy of vaporization, the highest is straight chain 1-alcohols, then 1-monochlorinated, and alkanes.

Task 2
In this task, there will be two different graphs. One is graph of boiling points of straight chains alkanes, straight chain 1-alcohols, and 1-monochloronated alkanes. Which the other graphs will be a graph for the enthalpy of vaporization. These two graphs are plot from data of Table 1, Table2, and Table 3.

Graph 1: Boiling Point (°C) based on Table 1, Table 2, and Table 3 data.

Graph 2: Enthalpy of Vaporization (kJ/mol) based on data on Table 1, Table 2, and Table

First as the basic we know that boiling points and vaporization occurs because of heat, where the substance that is being heated evaporated, most of the time the substance that is use usually are liquid phase. Then from here we can know that the theory related to this graphs is Latent heat of vaporization. Based on Food Processing Technology- Principles and Practice (2nd Edition), “During evaporation, sensible heat is transferred from steam to the food, to raise the temperature to its boiling point. Latent heat of vaporization is then supplied by the steam to form bubbles of vapor, which leave the surface of the boiling liquid. The rate of evaporation is determined by both the rate of heat transfer into the food and the rate of mass transfer of vapor from the food.”3 Where in this book, food is the substance

    The purpose of this experiment was to observe and measure the effect of an unknown solute on the freezing point of a solvent and to determine the molar mass (molecular weight) of said unknown solute. In the experiment, the solvent, cyclohexane, and the unknown solute “Spongebob” were used throughout the experiment. According to theory as the unknown (nonvolatile) solute was added in the solution the vapor pressure should have decreased. When the vapor pressure decreases the freezing point will decrease along with it in the solution. In the experiment the cooling curves corresponds with that hypothesis.…

    The trend that was recorded in the data can be shown in the average table (table 2) that the more carbon bonds in the alcoholic spirit the slower it took the water to rise to a 40-degree increase. Methanol has the lowest number of carbons bonded, so the least amount of energy is required to break the bonds, therefore it releases the energy the quickest, making it the fastest time. In comparison, octanol has the most bonds, making it the slowest time to warm up the water at 2.41 minutes slower than the methanol. This trend also occurred with the alcoholic spirit weight difference, as before and after each trial the weight of the spirit burners to understand which alcohol burned the most.…

    Cyclohexane was the more volatile liquid collected in fraction A. It is a more volatile compound compared to Toluene due to its structure, which compared to Toluene does not contain any double bonds nor does it have any dipole moments. Thus with a lower molecular weight and little to no intermolecular forces will boil at a lower temperature than Toluene. Toluene processes double bonds that result in a dipole moment at the methyl group increasing intermolecular forces and thus required more kinetic energy, heat, to boil. The polarity generated by the benzene ring is also an important concept in the separation during gas chromatography.…

    Multiple trials were carried out because the wrong method of distillation was used. At the first trial, simple distillation was used and the result wasn’t as expected. The boiling point of the alcohol product wasn’t the boiling point of the expected alcohol 2-methyl-2-pentanol. The boiling point of 2-methyl-2-pentanol is 120-122oC (ref.6); however, the boiling point of the alcohol product was about 76-80oC. Simple distillation is useful if the difference between 2 products boiling point is more than 100oC; however, the difference of boiling point between ether and 2-methyl-2-pentanol is less than 100oC, so this method cannot be used. Therefore, when the ether was distilled off, the alcohol vapor was carried over by ether vapor causing the lowered reading of the thermometer.…

    Intermolecular Forces

    From proceedingdiscussion, one might expect that both compounds should have the same boiling points because of their similar molecular weight (88.2amu) and since both alcohols contain hydrogen directly bonded to oxygen, and therefore each molecule possess hydrogen bonding as additional intermolecular forces. However, this is not so because the differences in boiling points between these two compounds cannot clearly be attributed to the molecular weight and hydrogen bonding alone. The key to understanding these trends is to realize that although both compounds have similar molecular weight, but they also have different molecular shape and size (surface area). The larger and elongated shape of 1-pentanol provides a greater surface area available for contact between molecules, resulting in corresponding increase in the strength of dispersion forces between them, thus higher boiling points. In contrast, the smaller and more branched, spherical compact shape of 3-methyl-1-butanol offers a smaller surface area available for intermolecular contact which lowers the strength of the dispersion forces, resulting in corresponding decrease in boiling points observed.…

    However, this temperature was lower than the boiling point of acetone, the most volatile solvent possibly present in the unknown solution, pointing to a source of error in the measurement of the temperature. This could have been due to an inaccurate thermometer or to an error in placing the thermometer too high. Because the boiling point was so low, the more volatile solvent was estimated to be acetone, which has a boiling point of 56.5°C. After fraction A was collected, the temperature of the stillpot was increased and should have produced a steady increase in a plot of the temperature versus total volume distilled while fraction B (a mixture of the two components) was collected, until a second plateau at the boiling point of the less volatile component. The temperature of the stillpot needed to be increased after collecting fraction A because the liquid left in the stillpot was then composed of a higher percentage of the less volatile component, with a correspondingly higher vapor pressure, meaning that it would boil at a higher temperature.…

    Alkanols consist of three levels known as primary, secondary and tertiary. Primary alkanols occur when the hydroxyl group bonds with the first carbon atom of the chain. Secondary alkanols form when the hydroxyl group bonds with the second carbon atom of the chain and tertiary alkanols occur when the hydroxyl group bonds with the third carbon atom of the chain. Both primary and secondary alkanols can be oxidized however tertiary alkanols cannot (ausetute, NA). As the number of Carbon atoms in the carbon chain increase, so does the boiling point of the fuel.…

    We notice that no change occur in appearance of oil even it being heat until 1900C. From the result obtained, we notice that the boiling temperature raise when salt and sugar is added but no changes occur when cornmeal and gelatin is added. Boiling point increase due to decrease of vapor pressure. Water does not vaporize easily because the surface area for water to escape to the surrounding is decreasing when solute like salt and sugar are added to it. More energy are required to increase the vapor pressure of sugar solution or salt solution to exceed the atmospheric pressure so that…

Overall, I found out that even thought there was a large temperature difference with ethanol, it used up more than double the amount of energy then propanol. Propanol didn’t have a large temperature difference…
