Experiment 8: Identification of an Adulterated Herb The purpose of this lab is to analyze the volatile oils of some herbs through TLC testing and then identify the adulterant in a sample. Unfortunately‚ we ran out of time to complete the lab; however‚ we were able to get through most of it‚ and were only missing the adulterant. The first step to identify our unknown samples was to create TLC plates that should results with each known compound and 95% hexane: 5% ethyl acetate‚ 90% hexane: 10%

Oil from Jackfruit Seeds In partial fulfillment of the requirement Research Submitted To: Mrs. Linda Mahomoc Submitted By: Lucy Mae R. Mendoza Chapter I Introduction Background of the Study Oil is a smooth‚ thick liquid that is used as a fuel and for making the parts of machines move smoothly. Oil is found underground. Oil has many uses. It helps the machines to work like vehicles‚ agricultural equipment and generators. Oil price hike is the

hydrocarbon and cyclohexene is an unsaturated hydrocarbon due to the presence of double bond.Both hydrocarbons produce carbon dioxide and water during combustion test. When the oxygen is limited‚ the product will be carbon monoxide and water. The alkenes are highly flammable and burn readily in air‚ forming carbon dioxide and water. In this experiment‚ the combustion of cyclohexene burns in an orange flame and produces relatively high amount of black soot. The black soot produced is actually carbon

Stereochemistry of Dihydroxylation Reactions Question: Can the stereochemical outcome of dihydroxylation reactions be determined by thin layer chromatography? Overview: In this experiment‚ you will perform two reactions that transform alkenes into diols. While similar in functional group transformation‚ these reactions may lead to stereochemically different products. The two possible products are diastereomers of one another‚ and therefore have different physical chracteristics. After

bromine has preference of making or breaking a bond over all other directions that it may have had available. In this case‚ Markovnikov’s rule is revealed to be the case in this situation that states that adding a protic acid represented as HX to an alkene (sp2 hybridized)‚ the hydrogen from that HX would be attracted to a carbon with the least alkyl groups and the halide (X) would become more attracted and will attach to the carbon containing more alkyl groups. Within the intermediate stage of the

But before going deeper on what these tests are‚ what first are the difference between their results which are the primary‚ secondary and the tertiary alcohols‚ aldehydes and ketones? Alcohols are compounds in which one or more hydrogen atoms in an alkane have been replaced by an -OH group. Note however that there are different kinds of alcohols and Alcohols are categorized into different classes depending on how the -OH group is

Multistep Synthesis of Tetraphenylcyclopentadienone In this laboratory experiment a synthesis was performed through several separate steps. The purpose of the experiment was to synthesize tetraphenylcyclopentadienone from benzaldehyde and to run reactions on carbonyl containing compounds. There was a total of three steps that led up to the synthesis of the final product‚ tetraphenylcyclopentadienone. The first step of the experiment was the condensation of benzaldehyde to yield

A principle concern in the fracking debate lies over the content of the “fracking fluid.” This fluid is used to increase pressure in shale formations and cause fractures that increase permeability and allow greater access and capture of liquid natural gas or other hydrocarbon products that would be otherwise inaccessible or require numerous more wells be drilled (He‚ Li‚ Liu‚ Barbot‚ Vidic‚ 2014). This fluid consists of water and chemical additives such as‚ “ friction reducers to optimize flow characteristics
