PURIFICATION OF ORGANIC COMPOUNDS AIMS: To isolate organic‚ inorganic and component from a given sample. To become acquainted with various separation methods. To examine the solubility behavior of the various compounds in a mixture using different solvents. INTRODUCTION A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some

Use this packet and your book to answer the questions throughout this packet. Organic Nomenclature - Alkanes‚ Alkenes‚ Alkynes Naming organic compounds can be a challenge to any chemist at any level. Historically‚ chemists developed names for new compounds without any systematic guidelines. In this century‚ the need for standardization was recognized. For simple molecules‚ the nomenclature system worked out by the International Union of Pure and Applied Chemists (IUPAC) works well. For complex

Let Us Face the Future: The Labour Party 1945 Manifesto At the very end of World War 2‚ the British people is craving for a change in the economic and social policies of their country. In fact‚ the Great Depression and pre-war Conservative governments were very disappointing : Chamberlain’s (from 1937 to 1940) and Churchill’s (from 1940 to 1945) governments were practically only based on foreign policy (because of the war and the progressive degradation of the British Empire)‚ and

Discuss three main ideas from the Communist Manifesto. The Communist Manifesto was written by Karl Marx and Friedrich Engels‚ and it was originally published in German in 1848. The basic premise of the publication is to demonstrate the difference between class structures‚ primarily the bourgeoisie and the proletariat. It is a hugely influential book‚ and it is still relevant in today’s modern society. 1. Bourgeois and Proletarians Throughout history‚ the discord between the bourgeoisie and the

SYNTHESIS OF TRANS-9-(2-PHENYLETHENYL) ANTHRACENE (A WITTIG REACTION) Introduction: The purpose of this experiment is to convert carbonyl compounds to alkenes using Wittig reaction. In this case we will be synthesizing Trans-9-(2-phenylethenyl) anthracene from benzyltriphenylphosphonium chloride and 9-anthraldehyde. We will also aim to obtaining a high percent yield and purity for the synthesis of Trans-9-(2-phenylethenyl) anthracene. The mechanism for this reaction goes thus:
