Campbell's Biology, 9e (Reece et al.) Chapter 4 Carbon and the Molecular Diversity of Life This chapter focuses on the chemistry of carbon and organic compounds. Students should be able to identify the nature of the bonds between carbon and other elements (nonpolar versus polar), the different types of weak bonds and interactions, the various types of isomers, the basic functional groups of organic molecules, and their relative solubility in water. The abiotic formation of organic molecules from inorganic molecules is important in the origin of life. Multiple-Choice Questions 1) The element present in all organic molecules is A) hydrogen. B) oxygen. C) carbon. D) nitrogen. E) phosphorus. Answer: C Topic: Concept 4.1 Skill: Knowledge/Comprehension

Chapter 10 Structure and Synthesis of Alcohols Organic Chemistry, 6th Edition L. G. Wade, Jr. Chapter 10 * Structure of Alcohols Hydroxyl (-OH) functional group Oxygen is sp3 hybridized. Versatile synthetic intermediates Chapter 10 Chapter 10 * Classification Determined by carbinol carbon atom: Primary: carbon with ?OH is bonded to one other carbon. Secondary: carbon with ?OH is bonded to two other carbons. Tertiary: carbon with ?OH is bonded to three other carbons. Aromatic (phenol): -OH is bonded to a benzene ring. Chapter 10 Chapter 10 * Classify these: Chapter 10 Chapter 10 * IUPAC Nomenclature Find the longest carbon chain containing the carbon with the -OH group.

Chapter 9 Alkynes Organic Chemistry, 6th Edition L. G. Wade, Jr. Chapter 9 * Introduction Alkynes (a.k.a. acetylenes) contain a triple bond. General formula is CnH2n-2. Two elements of unsaturation for each triple bond. Some reactions are like alkenes: addition and oxidation. Some reactions are specific to alkynes. Chapter 9 Alkynes in Nature Chapter 9 * Nomenclature: IUPAC Find the longest chain containing the triple bond. Change -ane ending to -yne. Number the chain, starting at the end closest to the triple bond. Give branches or other substituents a number to locate their position. => Chapter 9 Chapter 9 * Name these: propyne 5-bromo-2-pentyne

Alkenes are commonly described as unsaturated hydrocarbons because they have the capacity to react with substances that add to them. Alkanes, on the other hand, are saturated hydrocarbons and are incapable of undergoing addition reactions. 6.1 Hydrogenation of Alkenes The relationship between reactants and products in addition reactions can be illustrated by the hydrogenation of alkenes to yield alkanes. Hydrogenation is the addition of H 2 to a multiple bond, as illustrated in the conversion of ethylene to ethane. The reaction is exothermic and is characterized by a negative sign for ?H?. Indeed, hydrogenation of all alkenes is exothermic. The heat given off is called the heat of hydrogenation and cited without a sign. In other words, heat of hydrogenation = -?H?.

Alcohols and Alkyl Halides: Introduction to Reaction Mechanisms In this chapter we explore structure and reactivity in more detail by developing two concepts: functional groups and reaction mechanisms. A functional group is the atom or group in a molecule most responsible for the reaction the compound undergoes under a prescribed set of conditions. How the structure of the reactant is transformed to that of the product is what we mean by the reaction mechanism. 4.1 Functional Groups Table 4.1 lists the major families of organic compounds covered in this text and their functional groups. 4.2 IUPAC Nomenclature of Alkyl Halides The IUPAC rules permit alkyl halides to be named in two different ways, called functional class
