CONCEPTS IN ORGANIC CHEMISTRY • Inductive Effect : Inductive effect is defined as permanent displacement of shared electron pair in a carbon chain towards more electronegative atom or group. Types of Inductive effect : 1.Negative Inductive Effect : (—I effect‚ Electron withdrawing effect) when an electronegative atom or group (more electro negative than hydrogen)is attached to the terminal of the carbon chain in a compound‚ the electrons are displaced in the direction of the attached

Contents 1.0 Abstract Acetaminophen and aspirin are both well-known drugs that relieve pain and reduce fever. This report looks at acetaminophen as a potential substitute for a patient who is allergic to aspirin. Acetaminophen‚ a common analgesic drug that can be bought over the counter‚ was synthesised by Hormon Northrop Morse. With acetaminophen consisting of a benzene ring‚ an amide and an alcohol group‚ it has the ability to stop pain and reduce fevers. However‚ due to the state of technology

CHEM 2123 and 2125 – Organic Chemistry Lab I and II GUIDELINES FOR WRITING LAB REPORTS INTRODUCTION Writing reports in organic chemistry lab may differ from the way it’s done in general chemistry. One goal of this course is to introduce you to the record keeping methods used in research labs. Such methods are designed to organize experimental data in a format similar to that required for publication in major scientific journals. Here are some important considerations that apply in research settings

asses the pharmaceutical preparation of Panacetin‚ by using it ’s solubility along with other organic molecules. We know that Panacetin is made up of sucrose‚ aspirin and some other unknown substance. We know the substance has to be Phenacetin or Acetanilide. To help solidify our reasoning‚ we need a % recovery of 8-12% sucrose‚ 35-45% aspirin and 45-55% unknown. Sucrose for example is insoluble in dichloromethane‚ while aspirin is soluble in CH2Cl2‚ but not in H2O. The organic compound sodium hydroxide

You can tamp them down using a glass stirring rod. Don’t use metal. Allow the nitration reaction to proceed for about 15 minutes (Schönbein’s time was 2 minutes)‚ then run cold tap water into the beaker to dilute the acid. Allow the water to run for a while.
