Introduction For the last week‚ specific tests had to be applied to determine the unknown solid that was given out randomly. Physical tests‚ solubility test‚ characteristic tests‚ NMR spectrums‚ and IR spectrums were all utilized to distinguish the identity of the solid. These assessments and a couple additional tests will be utilized again to determine the unknown liquid that was given to us in class. The other characteristics that will be looked at will be the boiling point‚ refracted index‚ and

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

Preparation of methyl m-nitrobenzoate by nitration using methyl benzoate‚ nitric acid‚ and sulfuric acid Aileen Quintana TA: Sijie Tues/Thurs 11:50 42067 Introduction: The purpose of this lab was to explore the concepts of electrophilic aromatic substitution‚ specifically nitration by synthesizing methyl m-nitrobenzoate using methyl benzoate‚ nitric acid and sulfuric acid. This nitration is a type of electrophilic aromatic substitution. A

Lab 8- nitration of Methyl I Benzonate Date of experiment: INTRODUCTION: The nitration of methyl benzoate is an example of an electrophilic aromatic substation reaction. In the experiment the electrophile was the nitronium ion and the aromatic compound was methyl benzoate and with addition of nitrating solution Methyl 3-nitrobenzoate was the product. Methyl benzoate Methyl 3-nitrobenzoate MATERIALS AND METHODOLOGY: The procedures for this experiment

ALCOHOL Drinking alcohol is like taking a drug. It is a form of drug abuse‚ and drug addiction. This is a worldwide problem that many people are involved in. There are good effects of alcohol if it is in small amounts and in self-control. On the other hand there are bad effects‚ if you take for long time. The effects that a person will get are all based on certain factors like‚ how much and how often alcohol is consumed‚ the age of the person‚ when the person started and how long they have been

When the word alcohol is brought up‚ what do you think about? What comes to my mind is parties‚ and what people think they have to drink to have fun. Did you know that over 5‚000 people under the age of 21 die each year from alcohol-related car crashes‚ suicides‚ homicides‚ alcohol poisoning‚ and other injuries such as falls‚ burns‚ and drowning? Alcohol can be a very dangerous substance if not treated correctly and drank responsibly. Alcohol is a form of a drug but unlike the other drug‚ marijuana

________________________________________ Absorption Alcohol is absorbed from all parts of the gastrointestinal tract largely by simple diffusion into the blood. However the small intestine is by far the most efficient region of the gastrointestinal tract for alcohol absorption because of its very large surface area. In a fasting individual‚ it is generally agreed that 10% to 20% of a dose of alcohol is absorbed from the stomach (the volume of alcohol affects the absorption) and 75% to 80% is absorbed

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
