ORGANIC CHEMISTRY PRACTICAL WORK HANDOUT MEZIANE ep NEBIA, Assia The practical work in organic chemistry aims to allow students to learn the fundamental techniques used in organic chemistry (extraction, distillation, recrystallization, chromatography). These can be implemented to carry out: •A chemical reaction. • Identification and spectroscopic characterization of synthesized products. • Exploitation of experimental results to determine the mechanism or reactivity of chemical species. •Writing reports with complete scientific rigor. This Organic chemistry handout of practical work is intended for engineering students in the second year of the Higher School in Applied Sciences of Tlemcen – ESSAT.

Structure of Matter ALI-DAHMANE, Tewfik This document is primarily intended for first-year engineering students in preparatory classes for higher education institutions in science and technology. It covers the Chemistry 01 program (Structure of Matter). It may also be useful for undergraduate students in chemistry and biology, as well as medical students, as there are minor differences between the curricula of these fields. This document provides systematically and thoroughly solved exercises, designed to help students overcome their difficulties. It includes seven essential chapters, namely : Fundamental concepts; The particles of the atom; Light , the spectrum of the hydrogen atom, and Bohr’s theory; Atomic model based on quantum mechanics (wave mechanics); Periodic classification of element; Electronic structure of the molecule (Chemical bond) and finally the last chapter VII, is dedicated to corrected exercises. We hope that this manual will achieve its objectives, and we encourage the reader to share their critiques and comments. We thank them in advance.

The Complete Organic Chemistry Practice Packet Boulanouar, MESSAOUDI The complete organic chemistry practice packet is a book intended for undergraduate students enrolled in the first cycle of university, college and institution and constitutes an interesting support for chemistry teachers. The book is rich in exercises and fruitful explanations as well as examples that help its user and reader to assimilate each point covered in the organic course with a very simple and convenient presentation style that is increasingly useful to our dear students. In this book, the student will learn, in a first chapter, a certain number of essential rules and bases adopted by the International Union of Pure and Applied Chemistry (IUPAC) through multiple exercises to practice systematic and official nomenclature. These rules will allow him to name molecules in organic chemistry whether simple, multiple or even mixed with more than one function. In a second chapter, he will become familiar with the representations of molecules in 3D space and the different spatial arrangements known in chemistry in general. The notion of conformations treating simple molecules such as butane or cyclic molecules such as cyclohexane are well studied and their possible stability is largely detailed. On the other hand, the different types of configurations as well as the Cahn-Ingold-Prelog (CIP) sequential rules explaining them are also addressed to enable him to properly determine the geometric configurations E and Z or absolute configurations R and S and finally, the great notion of chirality and all that unfolds and derives from it such as; enantiomerism, diastereoisomerism and Fischer projection of optically active molecules are illustrated and demonstrated by explanatory diagrams. All these important notions are well incorporated I a set of very useful and chosen exercise practice. A third chapter is devoted to the study of the different electronic effects, namely the inductive electronic effects and the mesomeric electronic effects as well as their different applications in the explanation of different chemical properties such as the acidity and basicity of organic compounds and also the study of the stability of the reaction intermediates that enter into the reaction mechanisms. Good demonstration exercises are given, well explained and discussed in details. The fourth chapter encompasses the application of all the concepts learned in the three precedent chapters of applications cited above and is intended for the study of large classes of basic reactions known in organic chemistry such as: substitution, elimination and addition. These reactions will allow students to acquire the basic concepts necessary for understanding the reaction mechanisms of organic chemistry reactions
