Organic Chemistry II Lab Diels Alder Reaction Purpose: In this experiment a Diels-Alder reaction was used to form the products. Cyclopentadiene and maleic anhydride were reacted together to form cis-Norbornene-5‚6-endo-dicarboxylic anhydride. 7-oxabicyclo{2.2.1}hept-5-ene-2‚3-dicarboxylic anhydride was also produced through a Diels-Alder reaction with the combination of furan and maleic anhydride. Equation: Procedure: Part 1 In a flask equipped with

fire-related deaths? What is the major cause of residential fires? a) 2‚640 people died in a fire related death‚ not including firefighters. Smoking is the leading cause of fire-related deaths. Cooking is the Primary cause of residential fires. 2. How many people are bitten by dogs each year? How many people die from dog bites each year? What is the most common age for people to get dog bites? a. 4.5 million People are bitten by dogs every year. 10 to 20 people die each year from dog

The purpose of this experiment was to synthesize triphenylmethanol from a Grignard reagent. The Grignard reaction technique was used in this synthesis but due to the fact that it is such a strong nucleophile and base‚ it was important to prevent water from interfering with the Grignard reaction. Purity of the product was determined by measuring the melting point. Reagent Table: Structure Name Molecular formula Molar mass Density Melting point Boiling Point Diethyl ether C4H10O

Enzymes Reactions to Changes in Substrate and Inhibitors Benjamin J. Mora Coronado University of Texas Rio Grande Valley at Edinburgh Abstract Purpose for the experiments was to test the enzymes in various scenarios and see how changing this would affect the rate of reaction. The enzyme source used in the experiments was Turnip Extract. Concentrations of Turnip extract for activity 1 where o.5ml‚ 1.0ml‚ and 2.0 ml as for the rest of the activities 2 Through 4 stayed at a consistent concentration

The effect of temperature on the reaction rate: As the temperature increases it provides more kinetic energy to the molecules allowing them to move faster and with more energy the molecules can overcome the activation energy barrier and therefore the reaction occurs faster. 5. Since the proposed mechanism is a SN1 reaction the reaction got faster as the polarity increased. This is because SN1 reactions work best with polar protic solvents as they stabilize the carbocation. Therefore‚ as seen

where an actual attack occurs and the IDPS isn’t alarmed at all. The least desirable would definitely be the false negative‚ if an attack does occur and the IDPS doesn’t even alarm well what’s the point in even having it if it isn’t going to alarm. 2. What is a honeypot? How is it different from a honeynet? A honeypot is a decoy system that will lure potential hackers away from the networks critical systems. A honeynet is where the system subnet is constantly changing and it lures attackers away

How much is it? How does reaction time change with practice? THEORETICAL The reaction time is the amount of time required to sense astimulus‚ analyze its meaning‚ and respond. Acceleration is the rate of change of velocity. Velocity is speed with direction
