VSEPR Worksheet - Solutions
1)
What is the main idea behind VSEPR theory?
The main idea is that electrons don’t like to hang around near each other because
they repel each other. As a result, the atoms in a molecule tend to separate as
far as they can because their bonds repel each other.
2)
For each of the following compounds, determine the bond angles, molecular shapes,
and hybridizations for all atoms:
a)
carbon tetrachloride
Carbon is tetrahedral, 109.50 bond angle, and sp3
hybridized.
Chlorine is linear, has no bond angle, and is sp3 hybridized
b)
BH3
Boron is trigonal planar, 1200 bond angle, and sp2
hybridized.
Hydrogen is linear, has no bond angle, and no hybridization
c)
silicon disulfide
Silicon is linear, has a 1800 bond angle, and is sp
hybridized.
Sulfur is linear, has no bond angle, and is sp2 hybridized.
d)
C2H2
Carbon is linear, has a 1800 bond angle, and is sp
hybridized.
Hydrogen is linear, has no bond angle, and no
hybridization.
e)
PF3
Phosphorus is trigonal pyramidal, has a bond angle of
107.50, and is sp3 hybridized.
Fluorine is linear, has no bond angle, and is sp3 hybridized.
