What is the VSEPR theory used to predict?

• Bond Strength
• Polarity
• Molecular Shape
• Electronegativity

According to VSEPR, molecules adjust their shapes to keep which of the following as far away as possible?

• Pairs of valence electrons
• Inner shell electrons
• Mobile Electrons
• Electrons closest to the nucleus

 A lone pair is defined as

• A pair of bonding electrons
• One non-bonding electron
• A pair of non-bonding electrons
• A pair of electrons on the central atom

T or F: Lone pairs around the oxygen atom of a water molecule play no role in determining its molecular geometry?

• True
• False

Which shapes are altered by unshared pairs of electrons?

• Bent and Trigonal Pyramidal

• Trigonal Planar and Bent

• Tetrahedral and Trigonal Pyramidal

• Trigonal Pyramidal and Linear

What shape would a molecule have if it has 4 bonded pairs around its central atom? (It may help if you sketch this out)

• Linear

• Trigonal pyramidal
• Tetrahedral
• Linear

Which molecule would have this shape?
