Synthesis of Butyl Benzoate Using Phase Transfer Catalysis The objective of the experiment is to synthesize the butly benzoate by nucleophilic substitution and characterize it by IR spectroscopy. The percent yield of the final product is determined after the synthesis. Procedures: 2.0 mL of 1-bromobutane‚ 3.0 g of sodium benzoate‚ 5.0 mL of water‚ 4 drops of Aliquat 336‚ and a boiling stone were placed in a 50mL round-bottomed flask. The reaction mixture was refluxed for 1 hour and the flask

Questions and Hypothesis: Seed germination‚ plant growth‚ and sprouting of leaves are affected by several factors: supply of nutrients‚ water‚ exposure to sunlight‚ and conditions of surroundings. Due to certain stimuli in the surroundings plant “hormones” cause plants to behave in ways that ensure the most efficient use of resources while preserving the most energy. One stimulus to consider‚ is the exposure of plants to sunlight; when plants are just sprouting and are underground‚ the sti

I. Introduction: The purpose of this lab report is to differentiate between of Newton’s Third Law and Newton’s Second Law. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration

Abstract: In this Lab we used the chemical DPIP to detect the rate of succinate broken down by the mitochondrial solution. We detected the amount of DPIP in the solution with a spectrophotometer and measuring the absorbance of light at the 600nm range. DPIP is a useful chemical to use in this experiment because it goes from a blue color when oxidized to a colorless liquid (Ogura‚ 281)‚ this is due to the hydrogen ions and electrons released during the transitional step between succinate and fumarate

Hello Dr Buxbaum‚ Below is my weekly update for this week from 5th July ’16 to 6th July ’16. 1) VEP practice recording (Shank3 Mice): - I had scheduled a VEP session today and while recording‚ I got -156 uv in a 20 successive stimuli presentation. Following this‚ I had recorded successive 3 sessions below -100 uv. I’ll ask Hiro tomorrow if these 3 successive sessions would provide the confidence he needs to allow me to perform the VEPs on Shank3 cohort. Accordingly‚ I’ll schedule a session to provide

Stoichiometry I. Introduction/ Purpose: Stoichiometry is the study of the quantitative‚ or measurable‚ relationships that exist in chemical formulas and also chemical reactions. The calculations of a stoichiometry problem depend upon balanced chemical equations. The coefficients of the balanced equations indicate the molar ratio of the reactants and products taking part in the reaction. There are three major categories of stoichiometry problems such as mass-mass‚ mass-volume‚ and volume-volume
