RQ-25-Ch12s6-end
T or F It is important to identify lone pairs around a central atom because they do not repel other electron groups.
F
T or F The correct Lewis structure for CO2 shows that the carbon atom has two sets of lone pair electrons.
F
T or F The electron geometry of a molecule is never the same as its molecular geometry.
F
T or F Water and oil do not mix because water molecules are nonpolar and molecules that compose oil are generally polar.
F
T or F Boron forms compounds that violate the octet rule.
T
T or F The VSEPR theory predicts that the angle between the central carbon atom and the two oxygen atoms in CO2 measures 180°.
T
What is the term for a model that explains the shapes of molecules based upon electron pair repulsion about the central atom?
