VSEPR

What is the VSEPR theory used to predict?

• Bond Strength

• Molecular Shape
• Electronegativity

Which of the following shapes has unshared pairs of electrons on the central atom? 

• Bipyramidal
• Bent
• Trigonal Planar
• Tetrahedral

Which molecule would have this shape?

• BF₃
• CH₄
• PCl₅
• CO₂

What molecule could this be? 

• BF₃
• CH₄
• H₂O
• CO₂

Who could this molecule be?

• CH₄
• CO₂
• PCl₅
• BF₃

What shape would PH₃ have?

• Trigonal Planar

• Trigonal pyramidal

• Bent

• Linear

What molecular shape is the structure shown here? (BCl₃)

• linear
• trigonal planar
• tetrahedral
• trigonal pyramidal

What molecular shape is the structure shown here? (H₂O)

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

• Lone 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
