Document Summary

Topics discussed on sept. 9: fundamental principles of the electronic theory of organic chemistry, electrostatic properties of molecules. Milestones of organic chemistry: structural theory and electronic theory of organic chemistry (notes of sept. 7) Inability of the structural theory of organic chemistry to rationalize the chemical reactivity of carbon compounds. Electronic theory of organic chemistry: an intellectual framework that allows one to rationalize and predict the chemical reactivity of organic compounds on the basis of the electronic properties of their molecules (= how electrons behave within a molecule) Reminder: the electronic theory permits an approach to mastering organic chemistry that relies on logical reasoning, not on memorization. Electrostatic properties of molecules as important factors that influence their reactivity. Evaluating the electrostatic properties of molecules: formal charges, bond polarization, and oxidation states. Principle: atoms can produce bonded states in which significant electrostatic imbalance exists.
