RocketBoom - Essay Example Rocketboom has an organizational structure that differs from the traditional television programs that feature the unidirectional structure. It targets international audience by engaging them in discussions and in various formats and platforms (VCTV 2007). The Rocketboom video covers the top and new stories with a bias on international arts and weblog drama. It presents the videos online and also distributes them via RSS. The firmâ€™s content can also be accessed via its website, iTunes and subscription through emails. The availability of its content online gives it a larger audience than the television companies. Unlike traditional televisions that spend heavily in production, it uses simple facilities to compose its content (DeVilla 2006). Failure to understand the concepts of IT and business would have deprived it the opportunity to thrive in the hostile market. As discussed above, most traditional television companies fail to register growth because of their limited knowledge or lack of using IT exhaustively. Lack of business skills would have seen the company collapse at an early age because of poor
Introduction In an E1 reaction, where E stands for elimination and 1 stands for unimolecular. The breaking of the C-LV bond is completed before any reaction occurs between the base to lose a hydrogen and form the carbon-carbon double bond . When the more substituted alkene is the dominant product, the reaction follows Zaitsev's rule. Zaitsev's rule states that the major product of a ? -elimination reaction is the most stable alkene . Acid-Catalyzed Dehydration is the elimination of a molecule of water from adjacent carbon atoms.An alcohol can be converted to an alkene by dehydration, which is often brought on by heating the alcohol with either 85% phosphoric acid or concentrated sulfuric acid . The objective of this experiment is to dehydrate 3-methyl-3-pentanol to obtain the product mixture of isomeric alkenes 3-methyl-2pentene and 2-ethyl-1-butene. Then use the gas chromatography to separate the product mixture and analyze the composition .

Experimental The experiment started by gathering the supplies for distillation. In the vial, 2mL of 2-methylcyclohexanol and 1mL of phosphoric acid is added. The solvents are thoroughly mixed and a few boiling chips is added to help with the boil. The sand bath is set up with the thermometer and the sand will be heated up to 100oC and the vial containing the solvents will be placed on the sand and let to boil. The process should take about 30 minutes to start boiling.A beaker with a flask will be covered in ice and the water would be sucked out with the Pasteur pipette. When the distillation process is completed, the distillated liquid would be saved. CaCl2 would be added to the liquid to prevent evaporation and allows distillate to dry over drying agent. Then the little container will be weighed empty, and then the container with the liquid will be weight. Results ****** I canâ€™t figure out how to insert our graph. When I copy it my computer says it is too big to paste in a word document. So Iâ€™m going to pretend the graph is in this spot, and put the results of the graph under here.Hopefully someone else in the group can use their computer to insert the graph or we can print it off and the graph will just have its own page. A gas chromatogram is a plot of a response against the retention time. Chemical substances as gases are retained on the liquid column (stationary phase) with a flow gas being the carrier (mobile phase) through the column. At the end of the column is some means of detection. The peak height or the peak area is used to quantitate the amount of substance. The number of peaks can also help determine whether or not one is dealing with a pure compound.Peak one has a retention time of . 29 seconds and a peak area of 999. 00. Peak two was found to have a retention time of . 37 seconds and a peak area of 5067. 00. The percent composition for peak one is 16. 46884% and the percent composition for peak two is 83. 53116%. The percent yield is given by the ratio of the experimental yield to the theoretical yield, which was found to be 52%. Discussion All possible products were observed. Under kinetic control, a significant yield of 3-methlycyclohexane is expected when 2-methylcyclohexane is dehydrated.The kinetic product is known as Hofman product. The mechanism of this dehydration involves the formation of a tertiary carbocation intermediate. The observed products do support E1 mechanism. E1 mechanism indicates an elimination, unimolecularÂ reaction, where rate = k [R-LG]. This implies that the rate determining step of the mechanism depends on the decomposition of a single molecular species. The pathway involves two critical steps, which are the loss of the leaving group to generate aÂ carbocation intermediate, thenÂ the loss of a proton from the carbocation to form a pi-bond.In this experiment the slow step in this elimination is the loss of a water molecule (the leaving group) from the oxonium ion to form the carbocation intermediate. This unimolecular rate-determining step makes this an E1 mechanism. The percent composition of a compound is a relative measure of the mass of each different element present in the compound. It gives the composition of the sample that was injected into the gas chromatograph, which ultimately helps determine alkene stability. In an error analysis of this experiment, peak resolution is critical.In a good chromatographic separation, the components of the sample are completely separated from each other in the chromatogram. Unfortunately, an incomplete separation of the components in a sample gives poor peak resolution and there is an overlap between adjacent peaks in the chromatogram. When the peaks in a chromatogram are poorly resolved, it is necessary to adjust one or more of the separation parameters until baseline resolution is obtained. Reference  Brown, William Henry.
