2 cards from this section. Quick, good the night before a test.
Define an electron domain.
Think about what areas have concentrated electrons.
What is the bond angle for equatorial positions in a trigonal bipyramidal molecule?
Consider how many bonds are involved in the equatorial positions.
What type of molecular geometry is exhibited by five electron domains?
Think about how many positions there are and their angles.
True or False: Lone pairs do not affect molecular geometry.
Recall how lone pairs exert more force.
Given a molecule with the formula PF5, outline the steps to determine its molecular shape and bond angles.
Consider the number of atoms attached to the central phosphorus.
Analyze the molecular geometry of SeF4 and describe the resulting shape and bond angles, particularly focusing on the effect of lone pairs.
Remember to account for lone pair repulsion when visualizing the shape.
