1 Chapter 6.5 Quiz 5 Questions 25 points

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. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

3 According to VSEPR theory, the shape of an AB3 molecule is
1 According to VSEPR theory, the shape of an AB3 molecule is trigonal planar. linear. tetrahedral. bent. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

4 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. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

5 1 Compared with molecular bonds, the strength of intermolecular forces is weaker. about the same. stronger. too variable to compare. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
