McGraw Hill Higher Education, 2020. ISBN10: 1260148920, ISBN13: 9781260148923. Introduction to organic chemistry, Fourth Edition by William Brown and Thomas Poon, John Wiley and Sons 2011. ISBN 978-0-470-38467-1 Organic Chemistry, 9th Edition by T. W. Graham Solomons and Craig B. Fryhle, John Wiley and Sons, 2008. ISBN 978-0-471-68496-1 Introduction What is Organic Chemistry? ▪ Literally, the term “organic” means “derived from living organisms”. ▪ Organic chemistry was originally the study of compounds extracted from living organisms and their natural products. ▪ It was believed that only living organisms possessed the “vital force” necessary to create organic compounds (vitalism). ▪ This concept started to change in 1828 after Friedrich Wöhler showed that it was possible to make urea (a constituent of urine) by evaporating an aqueous solution of the inorganic compound ammonium cyanate: What is Organic Chemistry? ▪ The modern definition of organic chemistry is the chemistry of compounds containing carbon. ▪ Carbon Compounds are everywhere around us in food, flavors, fragrances, medicines, cosmetics, plastics, fibers, paints, adhesives and of course in our bodies (DNA and proteins). 11-cis-retinal Absorbs light and allows vision Why Carbon? 1. Carbon can form strong covalent bonds to other carbon atoms and other elements as: hydrogen, nitrogen and oxygen. 2. Carbon can form chains and rings. Principles of atomic structure Pure substances are either Elements or Compounds. Principles of atomic structure ATOM ▪ It is the smallest unit of ordinary matter that forms a chemical element. ▪ An atom consists of a dense, positively charged nucleus containing protons and neutrons and a surrounding cloud of electrons. ▪ Each proton of the nucleus bears one positive charge; electrons bear one negative charge. Neutrons are electrically neutral; they bear no charge. ▪ Protons and neutrons have nearly equal masses (approximately 1 atomic mass unit each) and are about 1800 times as heavy as electrons. Most atom mass comes from the mass of the nucleus; (electrons atomic mass is negligible). Principles of atomic structure Electronic Structure of Atom ▪ Electrostatic forces keep the electrons moving around the nucleus. These are the forces that pull negatively-charged and positively-charged particles towards each other. ▪ In nature, most atoms are stable. A stable atom has the same number of electrons as protons. Principles of atomic structure ▪ Each element is distinguished by 2 numbers. ▪ The Atomic Number (Z) a number equal to the number of protons in its nucleus. Because an atom is electrically neutral, the atomic number also equals the number of electrons surrounding the nucleus. ▪ The Mass Number (A) is the total number of protons and neutrons in an atom. Principles of atomic structure Volume of the atom ▪ Most of the volume of an atom comes from the electrons. ▪ The volume of an atom occupied by the electrons “electron cloud” is about 10,000 times larger than that of the nucleus. ▪ Electron Cloud contributes very little to the mass of the atom, but make up most of the volume of the atom. Principles of atomic structure Isotopes They are two or more types of atoms that have the same atomic number and position in the periodic table, and that differ in mass numbers due to different numbers of neutrons in their nuclei.
