Document Summary

Practice exam, here tonight, 7 9 pm. Sat (10/23) at 3 pm in this room. 2. 7 & 2. 8 (covalent bonding), 3. 0-3. 2, 9. 3 (covalent bonding), 9. 5 (electronegativity), 10. 0-10. 2, 11. 0-11. 2. Due at the beginning of class monday, 10/25. Hybridization: when atomic orbitals mix to form new hybrid orbitals. Sp3 from one s and 3 p orbitals, tetrahedral class. Sp2 from one s and 2 p orbitals, trigonal planar class. Sp from one s and one p orbital, linear class. 1 s, 3 p, and 1 d sp3d orbitals. Must have d orbitals for this only period 3 and larger. 1 s, 3 p, and 2 d 6 sp3d2 orbitals. # of lone pairs (or # of bonded atoms) What is the shape of the molecule: sp2 bent, sp3 tetrahedral, sp2 trigonal planar, sp3 bent. Can"t be b or c not enough groups. For the best resonance form of cocl2 (c is the central atom), what is the hybridization of.
