Molecular Shapes Flashcards
1
Q
VSPER Theory:
A
Valence shell electron pair repels themselves as far apart as possible in the 3-Dimensions of space.
2
Q
How are shapes formed?
A
Shape adopted by a simple molecule or ion is that which keeps all repulsive forces to a minimum.
3
Q
Linear
A
BP: 1 OR 2, LP: 0, Angle: 180˚
4
Q
Triangular Planar
A
BP: 3, LP: 0, Angle: 120˚
5
Q
Tetrahedral
A
BP: 4, LP: 0, Angle: 109.5˚
6
Q
Bent
A
BP: 2 or 2, LP: 2 or 1, Angle 104.5˚ or 120˚
7
Q
Pyramidal
A
BP: 3, LP: 1, Angle: 107˚
8
Q
LP Pairs vs BP:
A
LP have a greater repulsive force than BP.
- When LP present, bond angle is greater.
