Conversion of Alcohols to Alkyl Halides Title: Conversion of Alcohols to Alkyl Halides Abstract: In this experiment the conversion of alcohols to alkyl halides are investigated through reflux and simple distillation. These are common procedures used to separate substances. After the reflux and distillation is complete 13C NMR and IR spectrum is used to identify the product or products for each reaction: 1a‚ 1b‚ and 2. Every individual in the group was assigned either 1a (1-propanol) or 1b (2-pentanol)

hematology market is estimated to grow at a lower CAGR in developed countries; however‚ it is expected to witness high growth in emerging countries such as China‚ India‚ and Brazil in the next five years. The growth of the Hematology analyzers and Reagents market is driven by factors such as increasing adoption of automated hematology instruments by diagnostics laboratories‚ growing development of the high throughput hematology analyzers‚ integration of basic flow-cytometry techniques in modern hematology

The Grignard Synthesis of Triphenylmethanol Abstract: Grignard synthesis of triphenylmethanol was achieved by use of the Grignard reagent phenyl magesium brominde. The organometallic grignard reagent was synthesized by use of a reflux apparatus recrystallization techniques. Once synthesized it was used in a Grignard reaction that involved nucleophilic addition to a carbonyl in order to make triphenylmethanol. The final product was solidified and recrystallized and spectral data was

along with limiting reagent analysis. The reaction of Copper (II) Sulfate‚ CuSO4‚ mass of 7.0015g with 2.0095g Fe or iron powder produced a solid precipitate of copper while the solution remained the blue color. Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was found to be 2.1726g which meant that through limiting reagent analysis Fe was determined to be the limiting reagent and the chemical reaction

When there is H2O and snails in the bromthymol blue‚ the reagents will be neutral‚ then the results will be same with the reagent in light and dark. When there is H2O and plants in the bromthymol blue‚ the reagents will be basic‚ as the same with the light one and dark one. When there are H2O‚ plants and snails in the bromthymol blue‚ the reagents in light will turn to neutral but more about basic‚ and the reagents in the dark will be neutral.
