What defines a polar covalent bond?
Think about differences in electronegativity.
Name a nonpolar molecule.
Consider molecules that are homonuclear.
What is a dipole moment?
It's related to charge and distance.
True or False: Polar bonds in a molecule always result in a polar molecule.
Consider the geometry of the molecule.
Given the molecular structure of ammonia (NH3), predict its polarity and explain the reason based on bond dipoles.
Consider how the shape influences the sum of bond dipoles.
Analyze the structure of carbon dioxide (CO2) for polarity. Discuss how its shape influences its overall polarity.
