Sarah Muhs ID: 11325862 Nitration of Methyl Benzoate Post Lab: 1. Is the ester group of your starting material electron donating or withdrawing? Support your conclusion with resonance drawings. The ester group‚ CO2CH3‚ of the starting material was electron withdrawing. 2. Draw the mechanism of the nitronium ion reaction with the methylbenzoate. 3. Why does water stop the reaction? Water stops the reaction because of Le Châtlier’s principle. Since water is a product‚ when more is added it drives

Eating junk food can have a significant impact on one’s health. Though many people enjoy eating junk food and think it tastes great‚ the health consequences can be serious‚ and can range from everything to low energy levels to weight gain and illness. The term "junk food" encompasses a fairly broad category of food‚ but it typically refers to foods that are relatively high in caloric content‚ but low in nutritional value. Junk food is often high in sugar‚ salt‚ white flour‚ and fat‚ particularly saturated

The Effect of pH on the Rate of Osmosis Using a Glucose Solution Melissa Werderitch Biology 157 11/6/06 Introduction In a journal article written by Florian Lang‚ osmosis is essentially explained as the flow of water from one area to another that are separated by a selectively permeable membrane to equalize concentrations of particles in the two locations (Lang‚ 1997). Osmosis is able to maintain osmotic pressure and regulate a cell’s volume. In a hypotonic () or hypertonic () environment

Title: Experiment 28: Nitration of Methyl Benzoate Objective: The students will learn to nitrate methyl benzoate through electrophilic aromatic substitution reaction. They will learn the importance of regiochemistry in chemical reactions. They might experience disubstitution through a high temperature. Reactions: Observation: The crystals started to form when added 2 g of crushed ice. The addition of hot methanol dissociated the crystals. The crystals reappeared when cooled down in

MEASURING pH Date of Lab: 02/09/13 Date Report submitted: 02/26/13 Purpose of the experiment By doing this experiment‚ we were trying to learn how to measure a pH with a pH meter to determine whether a solution is weakly‚ moderately or strongly acidic or basic; but also to compare the different data founded to see how the addition of certain liquid to a solution may affect the pH of the initial solution. Materials We used: * Tap water‚ distilled water‚ Soda and milk as the main

KNES 470 Dr Rubin 4-18-12 Sodium Bicarbonate and Boxing Performance Boxing is a sport which relies on anaerobic power since it contains short-duration and high intensity work. A typical boxing match today consists of 3 minute rounds with a 1 minute seated recovery rest. When an athlete performs exercise at maximal level for more than 30 seconds‚ most of the energy comes from anaerobic glycolysis. During this process‚ lactic acid is produced which causes a decrease in pH levels within the muscle
