Organic Chemistry Lecture 2
Chapter 2 ? 2010, Prentice Hall Organic Chemistry, 7th Edition L. G. Wade, Jr. Structure and Properties of Organic Molecules Chapter 2 * Wave Properties of Electrons Standing wave vibrates in fixed location. Wave function, ?, is a mathematical description of size, shape, and orientation. Amplitude may be positive or negative. Node: Amplitude is zero. Chapter 2 Chapter 2 * Wave Interactions Linear combination of atomic orbitals: between different atoms is bond formation. on the same atom is hybridization. Conservation of orbitals Waves that are in phase add together. Amplitude increases. Waves that are out of phase cancel out. Chapter 2 Chapter 2 * Sigma Bonding Electron density lies between the nuclei. A bond may be formed by s?s, p?p, s?p, or hybridized orbital overlaps.
