1.1 - Nomenclature 1 What you will be Learning Three major topics are covered in you journey to understanding organic chemistry: a) nomenclature, b) atoms and chemical bonds and c) chemical reactions and mechanisms. Nomenclature: Naming of organic compounds – The Basics If you do not learn the names of compounds you will not be able to follow along in class. It’s like your Dad asking you to get the dohicky from behind the thingamajig that’s in the garage. All you know is you have to go to the garage but you have know idea what he is talking about. You don’t want this to happen in class. You may know I am talking about an E 2 reaction but what the heck is a t -butoxide ion???? Nomenclature will be covered quickly and you will have to master it by completing Assignment #1 and the recommended questions in the text book. ONLY BASIC NOMENCLATURE WILL BE ASKED ON THE EXAMS In this course we will not be focus on applications but fundamental Science. You need to understand how and why a chemical reaction occurs before you can apply this knowledge to biological systems or devices. Once you understand these process your ability to create becomes boundless.

1.1 - Nomenclature 2 Atoms and Chemical Bonds: To understand how or why a chemical reaction takes place you must first understand atomic properties and the nature of chemical bonds. This is accomplished by investigating the following topics; trends in the periodic table, Lewis structures, formal charges, resonance structures, valence shell electron pair repulsion theory (VSEPR), valence bond theory and molecular orbital theory . These topics will provide you with a good understanding of intramolecular forces and the energies involved in creating bonds through the hybridization of atomic orbitals . Intermolecular forces or the bonding between molecules will also be studied through the examination of the physical properties of organic compounds. This is a review of first year chemistry but don’t take it lightly!! These theories are so important in the understanding of organic chemistry that we go over them again to make sure you comprehend them thoroughly. For example, could you calculate the formal charges on the atoms shown in the reaction given below?

3 Chemical Reactions and Mechanisms: To become fluent in the language of organic chemistry you must learn why chemical reactions occur. The first step to fluency is to study Bronsted-Lowry and Lewis acid-base reactions . This is examined first because acid-base reactions will be encountered in almost every topic in organic chemistry and when looking at the broadest sense of Lewis acids and bases, most organic reactions are in fact acid-base reactions. 1.1 - Nomenclature Organic molecules are then studied in greater detail by examining their conformational changes and the spatial arrangement of atoms in a molecule or stereochemistry ”. At this stage of the course you will have learnt the fundamental language of organic chemistry and now you must learn how to use the fundamentals to become fluent in the language. Without full understanding of these
