Difficulty: E101.In a Lewis structure for a molecule or ion, the sum of the formal charges on the atoms isequal to the charge on the molecule or ion.
Difficulty: E102.In formaldehyde, CH2O, both the formal charge and the oxidation number of carbon are zero.
Difficulty: M103.Boron never achieves an octet in any of its compounds.
Difficulty: M104.The Lewis structure of NO2violates the octet rule.
Difficulty: M105.Bond angles of 180° only occur around atoms which display linear molecular geometry.
Difficulty: M106.In order for a non-cyclic triatomic molecule to be bent, VSEPR theory requires that there must be two lone pairs on the central atom.

Chapter 10: The Shapes of Molecules107.According to VSEPR theory, a molecule with the general formula AX3E2(where E represents a lone pair on A) will be trigonal planar.
Difficulty: M108.The molecule AX2, where A and X are different elements, will have a dipole moment if the molecule is bent.
Difficulty: E109.A molecule which contains polar bonds will always have a dipole moment.
