GENERAL CHEMISTRY REVIEW

LESSON 4 OF 4

Electronegativity & Bond Polarity

Why are some chemical bonds nonpolar, others polar, and still others ionic? In this lesson, we'll use the idea of a tug-of-war over electrons to build an intuitive understanding of electronegativity and bond polarity. We'll explore periodic trends in electronegativity, compare nonpolar covalent, polar covalent, and ionic bonds. These concepts provide the foundation for understanding reactivity throughout organic chemistry.
