1 Lecture 13 Covalent Bonding Covalent Bonding 8.1 Single Bonds and Lewis Structures 8.2 Single Covalent Bonds in Hydrocarbons 8.3 Multiple Covalent Bonds 8.4 • Understand the concept of the covalent bond • Draw Lewis structures of molecules with single and multiple bonds • Hydrocarbons and other molecules with single bonds • Functional groups in organic compounds Lecture 13, Knowledge and Skills Covalent Bonding sharing of electrons between atoms H . + H . ± H:H Lewis recognized that atoms share electrons when they form bonds with each other. . H H H H In chemical bond formation an atom gains or loses electrons, or shares pairs of electrons, until its valence shell has eight electrons. This rule holds for most main group elements. For hydrogen the number of electrons is two. Octet Rule: Lewis Symbols Sulfur: element symbol ± S Group 16 ± 6 valence electrons Valence of sulfur is normally 2 Paired electrons Unpaired electron S S H H S .
