bent

Front

What is the molecular shape called when there are three bonding pairs and one lone pair of electrons?

Back

trigonal pyramidal

Front

What does the VSEPR rule state about molecular shape?

Back

A molecule will adjust its shape so that valence electron pairs stay as far apart as possible.

linear

Front

What is the molecular shape called when there are three bonding pairs and no lone pairs of electrons?

Back

trigonal planar

tetrahedral

Front

Define VSEPR theory.

Back

Valence Shell Electron Pair Repulsion theory is used to predict the geometry of individual molecules based on the repulsion between electron pairs.
