CHEM 3492: CHEM 3492

Uncover the distinct behaviors of hydrochloric acid and acetic acid in water. Learn about the complete ionization of strong acids and the partial ionization of weak ones, emphasizing the differentiation in proton donation.

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
