Molecular Geometry

Question 1

What properties does the shape of a molecule effect?

Answer 1

• shape impacts polarity which impacts intermolecular forces which impacts physical
  properties
• the shape of drug molecules and enzymes are responsible for their bioactivity
• the shapes of large, complex molecules can be understood by focusing on the shape
  around each central atom

Question 2

What is the valence shell electron pair repulsion (VSEPR) theory

Answer 2

The concept that electron groups (?!?) around an atom want to get as far away from one another to minimize repulsion

The maximum separation of electron groups around an interior/central atom
leads to the shape of a molecule

Question 3

What can be classified as an electron group?

Answer 3

a single bond is one electron group
a double bond is one electron group
a triple bond is one electron group
a lone pair is one electron group
a single electron (in a radical species) is an electron group

Question 4

molecular geometry

Answer 4

The spatial arrangement of ONLY the BONDS around a central atom
