  2. 1 According to VSEPR theory, the electrostatic repulsion between electron pairs surrounding an atom causes • an electron sea to form. • positive ions to form. • these pairs to be separated as far as possible. • light to reflect.

  3. 1 According to VSEPR theory, the shape of an AB3 molecule is • trigonal planar. • linear. • tetrahedral. • bent.

  4. 0 The intermolecular attraction between a hydrogen atom bonded to a strongly electronegative atom and the unshared pair of electrons on another strongly electronegative atom is called • electron affinity. • hydrogen bonding. • covalent bonding. • electronegativity.

  5. 1 Compared with molecular bonds, the strength of intermolecular forces is • weaker. • about the same. • stronger. • too variable to compare.

  6. 3 The following molecules contain polar bonds. The only polar molecule is • CCl4 • NH3 • CO2 • CH4
