​Molecular Geometry & Polarity (VSEPR)

By Alex Davila

SWBAT: determine molecular shapes using VSEPR theory and explain how shape and symmetry determine molecular polarity.

CO₂ is nonpolar (linear symmetry) while H₂O is polar (bent).

Which one is Polar? Which molecule is polar overall?

lone pairs bend geometry, creating unequal dipoles.
