Valence Shell Electron Pair Repulsion (VSEPR) theory is a chemical model built on the idea that —

•  bonded atoms form the shape in which the repulsions between pairs of electrons are minimized

•  bonded atoms form the shape in which the repulsions between pairs of electrons are maximized

Molecular geometries are —

• predictable

• unpredictable

• dependent on the repulsion between electrons

• the three-dimensional shapes of compounds

Which of the following are indicated by the model shown?

• the identity of the compound

• molecular geometry

• bond angles

• None of these

What is the correct molecular geometry for the model shown?

• Tetrahedral

• Trigonal Planar

• Trigonal Pyramidal

• Bent
