In order to successfully synthesis the reactant to the product‚ NaBH4 was used as the main reagent to reduce the carbonyl double bond. One believes the formation of isoborneol was successfully due to the product’s percent yield‚ IR‚ and melting point. During the lab‚ .077 grams of isoborneol was yielded from the camphor reduction. In result‚ .077 g compared to an theoretical yield of .102 g equaled an overall 75% percentage yield. Considering the product yield was only a quarter shy of a 100% yield

Ben Quinones AP Chem Mr. Perry 25 January 2013 Molar Mass by Freezing Point Depression Conclusion: My Lab unsuccessfully found the molar mass of the unknown given to us in the lab. We were tasked with finding the molar mass of an unknown compound using the colligative property of Freezing Point Depression. The way we did this was first finding the temperature at which ice crystals form for just regular BHT. Luckily thanks to our TA we were given temperature probes so we could pinpoint exact

Exploring Boiling Points Introduction: Every substance has a unique set of properties that allow us to differentiate between them. These properties are classified as physical properties and chemical properties. Physical properties are those that can be determined or measured without changing the composition or identity of the substance. These properties include color‚ odor‚ taste‚ density‚ melting point‚ boiling point‚ conductivity‚ and hardness. Chemical properties tell us how the substance

reproductive. Orientation is when the organism is placed in their beneficial environment consisting of two behaviors‚ taxis (movement directly towards or away something) and kinesis (random movement). Reproductive is detected using drosophila in this lab‚ it consists of finding courting and mating with another of the species Agnostic behavior is found in a situation where the animal feels threated by another‚ leading to the organism looking bigger or more threatening to the opponent. Within the Agnostic

anhydride.The goal of this experiment was to determined the purity of aspirin using different methods. These methods included‚ reacting salicylic acid with FeCl3‚ finding its melting points‚ and by doing Thin-layer chromatography. When you reacted salicylic acid with FeCl3‚ changes in color will occur. Pure Aspirin has a melting point around 135°C and a pure salicylic acid has 158 °C. TLC is used to separate compounds based on affinity for stationary phase or mobile phase. In TLC‚ the solvent went up at

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

Introduction: In the lab‚ Bromide was combined with trans-cinnamic acid in order to see if the resulting product at the end of the experiment would yield either an erythro- or threo-dibromide. Based on how well this experiment was done there is a possible product that would have a melting point around 95°C‚ threo-‚ 205°C‚ erythro-‚ or somewhere in the middle which would be a combination of the two. The process of refluxing was used to purify the mixture followed by crystallization. In the end
