In this lesson, we explore polar and nonpolar covalent bonds and learn how electronegativity differences affect the way electrons are shared in molecules.
You’ll learn:
• How electronegativity determines bond polarity
• How to identify polar vs. nonpolar bonds
• The meaning of partial charges (δ+ and δ−)
• The difference between bond polarity and molecular polarity
• How molecular geometry and symmetry determine whether a molecule is polar overall
• The basics of sigma (σ) and pi (π) bonding
We’ll also examine how polarity influences real-world properties such as boiling point, hydrogen bonding, and the unique behavior of water.
By the end of this lesson, you’ll be able to analyze both bond polarity and molecular geometry to determine whether a molecule is polar or nonpolar.
This lesson connects structure, geometry, and intermolecular forces — an essential step toward understanding chemical behavior and reactions.
