Chemistry Project on Evaporation of Liquid Acknowledgement I would like to show my gratitude to my Chemistry Teachers Ms Seema More without whose support and encouragement this project could never have have taken the present shape . I would also like to thank my lab incharge Mr. Kakde For helping Me out During The Practical Part Of This Project. Aim Acknowledgment I am are greatly thankful for the cooperation and help from the Community Science Center (CSC) authorities and the Chemistry lab

reactions are an important class of reactions because of their synthetic utility and importance in understanding the mechanism of a variety of organic reactions. Materials & Methods: (Effect of Structure of the Alkyl Halide) 2mL of 15% of NaI in acetone was put into three test tubes. Two drops of 1-bromobutane were added to the first test tube. Two drops of 2-bromobutane were added to the second test tube. Two drops of 2-methyl-2-bromobutane were added to the third test tube. The test tubes were

a man-made matter constructed by a A. Dianin‚ a Russian scientist‚ in 1891. When the examiner first tried working on synthesizing bisphenol A‚ he came up with two phenol groups‚ which have a chemical formula of C6H6O‚ and integrated them with an acetone group‚ which has a chemical formula of C3H6O. This whole process of producing bisphenol A required a third substance that would effectively maximize the rate of the reaction. Mr. Dianin then realized that the only thing that would noticeably accelerate

Laboratory #6 Qualitative Tests for Carbonyls: Aldehydes vs. Ketones Introduction Various chemical tests identifying ketones and aldehydes are used in this experiment in order to identify an unknown carbonyl compound. The tests used are: 2‚4-dinitrophenylhydrazone test‚ Tollen’s Test‚ Benedict’s Test‚ Chromic Acid Test‚ aka Bordwell-Wellman Test‚ Schiff’s Test‚ and Iodoform Test. These classification tests provide results based on color change or formation of precipitation‚ which is then used

described. In order to convert these substances into safrole (III) and o-safrole (IV)‚ respectively‚ methylenation was carried out‚ with moderately good yields‚ by gently refluxing them with methylene iodide and anhydrous potassium carbonate in dry acetone solution. By employing such mild conditions‚ any change into the isomeric isosafroles during the course of the reaction was inhibited. The identity of the synthetic product with naturally occurring safrole has been established by preparing the pentabromo-derivative

We reached our goals through our experimentation. We tested the solubility of each of the starting and ending materials in water‚ HCl‚ NaOH‚ toluene‚ and acetone. We discovered that the starting materials would only dissolve in toluene. To make the soap‚ we obtained about 10 mL of vegetable oil and 10 g of lard and we placed them both in separate 250 mL beakers. While we were stirring the compounds‚ we also added 15 mL of 6 M NaOH drop by drop and 1 mL of glycerol. We then heated our solutions

As with Lard none of the liquid dissolved with it. Adding the soap to the solids also didn’t dissolve anything. For the second station‚ Acetone had the lowest boiling point with 60 °C‚ then Hexane with 62 °C‚ Ethanol with 80 °C and lastly Water with the highest boiling point of 85 °C. For the third station‚ with the highest and lowest viscous‚ Hexan had the lowest viscous of 2.03‚ third was

Results and Discussion Problem: Identifying which liquid evaporates faster Hypothesis: Acetone evaporates faster than kerosene‚ water and alcohol. Conduct an Experiment: Get .3 mL of each liquid Observe it for 3 minutes until it evaporates Gathering Data: Kerosene = 2 minutes and 3 seconds Water = 3 minutes and above Acetone = 1 minute and 22 seconds Alcohol = 1 minute and 52 seconds Conclusion: Acetone is evaporates faster than the other liquids such as alcohol‚ kerosene and
