CHEM 212: General Chemistry II

This discussion revolves around the classification of chemical bonds as ionic, polar covalent, or covalent based on the electronegativity difference between the atoms involved. The general criteria for this classification are explained: a difference greater than 1.7 indicates an ionic bond, between 0.5 and 1.7 signifies a polar covalent bond, and less than 0.5 designates a covalent bond. It then applies these criteria to four specific examples, including the CC bond in ethane (H?CCH?), the KI bo
