CHM 303 1st Edition Lecture 3 Outline of Last Lecture I. StructureA. Ionic BondsB. Covalent Bonds1. Lewis structures2. Formal charges3. Resonance4. Dipole momentsOutline of Current LectureI. StructureA. Covalent Bonds5. Expanding the octet ruleII. Structural Formulas of Organic MoleculesIII. Using Curved Arrows in ChemistryCurrent LectureI. StructureA. Covalent Bonds5. Expanding the octet rule-Adding protons increase electronegativity*dipole moment (μ)= amount charge (e) x distance between charges (d)*These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.First two rows (s and p) do not allow for octet expandingWant 3rd level available for bonding (d). II. Structural Formulas of Organic MoleculesWhen drawing possible structures;1. Draw Carbon skeleton2. add Hydrogen and other elements3. Write condensed form**Constitutional Isomers: 2 or more different compounds from same formula**III. Using Curved Arrows in Chemistry1. Use single-barbed arrow to depict moving one electron2. Use double-barbed arrow to depict moving two
