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

Worksheet ? Hybridization One model to explain bonding in molecules is called the valence bond theory. It is based on the concept of hybridized molecular orbitals. Atomic orbitals (s,p,d) are mathematically mixed to form molecular orbitals with defined shapes and energy levels. In organic chemistry, we need only look at the hybridization of the one 2s and three 2p orbitals containing the valence electrons of C,O and N. When four equivalent molecular orbitals are needed, all four atomic orbitals are mixed to give sp3 hybridization. When three equivalent molecular orbitals are needed, three of the atomic orbitals are mixed to give sp2 hybridization. In this case, one unhybridized p atomic orbital remains, with its shape and energy level

AP CHEM LAB: CHEMICAL BONDING ? POLAR OR NONPOLAR THEORY: ?Two atoms held together by the mutual attraction of each nucleus to valence shell electrons are said to be chemically bonded. The chemical bond can be represented by the overlap of the electron probability density map of an atomic orbital from each atom to form a molecular orbital capable of containing two electrons. Or said in English, a covalent bond can form. These electrons are shared between the respective atoms. However, the degree of sharing is not necessarily equal. The electronegativity of each atom can be used to approximate its attraction for the electrons and therefore the probability of finding the electrons closer to that nuclei.
