Shapes of Molecules and Intermolecular Forces Flashcards
If the shape is linear, then what is the bond angle and how many bonds are there?
180° and 2 bonds.
If the shape is trigonal planar, then what is the bond angle and how many bonds are there?
120° and 3 bonds.
If the shape is tetrahedral, then what is the bond angle and how many bonds are there?
109.5° and 4 bonds.
If the shape is a trigonal bipyramid, then what is the bond angle and how many bonds are there?
90° and 120° and 5 bonds.
If the shape is octahedral, then what is the bond angle and how many bonds are there?
90° and 6 bonds.
If the shape is pyramidal, then what is the bond angle and how many bonds are there?
107° and 3 bonds.
If the shape is non-linear, then what is the bond angle and how many bonds are there?
104.5° and 2 bonds.
What are the two types of electron pairs?
Bonding pairs and Lone Pairs.
On average, how far do lone pairs repel electrons from themselves.
2.5° per lone pair.
How do electron pairs repel?
They repel as far apart as possible.
Why do lone pairs distort the shape of a molecule?
They repel more strongly than bonding pairs of electrons.
