Chapter 9

Question 1

Valence shell electron pair repulsion (VSEPR) theory:

Answer 1

used to allow us to convert lewis structure into 3D structures.

Question 2

Hybrid orbital theory:

Answer 2

allows us to predict and understand the 3D structure of molecules and provides a localized description of the role of orbitals in covalent bonding

Question 3

Molecular orbital binding (MO) theory:

Answer 3

describes a delocalized description of the role of orbitals in a covalent bonding that is useful for explaining the reactivity of molecules and the interactions of molecules with electromagnetic radiation

Question 4

Linear

Answer 4

• Things: 2
• Hybridization: sp
• Bond Angles: 180
• Lone Pairs: 0

Question 5

Trigonal Planar

Answer 5

• Things: 3
• Hybridization: sp2
• Bond Angles: 120
• Lone Pairs: 0

One pair = Bent

Question 6

Tetrahedral

Answer 6

• Things: 4
• Hybridization: sp3
• Bond Angles: 109.5
• Lone Pairs: 0

One Pairs = Trigonal Pyramidal
Two Pairs = Bent

Question 7

Trigonal Bipyramidal

Answer 7

• Things: 5
• Hybridization: sp3d
• Bond Angles: 90, 120
• Lone Pairs: 0

One Pair= See-saw
Two Pairs= T-shaped
Tree Pairs= Linear

Question 8
