NOV 1: THEORIES OF CHEMICAL BONDING & MIDTERM REVIEW 7.9 - Name the hybrid orbitals formed by combining the following sets of atomic orbitals: (a) one 3s and three 3p orbitals; (b) one 2s, and one 2p orbital; and (c) one 3s, three 3p and two 3d orbitals. 7.11 - Identify the hybridization of the underlined atom in the following species: (a) (CH3)2NH; (b) SbF5 ; (c) SO2 ; and (d) CS2 7.17 - Describe the bonding of hydrazine (H2NNH2). Sketch an orbital overlap picture of the molecule. 7.30 - In each of the following pairs, which has the stronger bond? Use orbital configurations to justify your selections: (a) O2 or O2+; (b) CO or CO−; and (c) F2 or F2+. 7.32 - For each of the following interactions between orbitals of two different atoms, sketch the resulting molecular orbitals. Assume that the nuclei lie along the z-axis, and include at least two coordinate axes in your drawing. Label each MO as bonding or antibonding and σ or pi. (a) 2pz and 2pz; and (b) 2py and 2py. 7.34 - The superoxide ion (O2−) is a reactive species that may play a role in the chemistry of aging. Describe the bonding in this ion.
