Problem 83

Use the periodic table inside the front cover of this text to determine the atomic mass (per mole) or molar mass of each of the substances in column 1, and find that mass in column 2. Column 1 Column 2 (1) molybdenum (a) 33.99 g (2) lanthanum (b) 79.9 g (3) carbon tetrabromide (c) 95.94 g (4) mercury(II) oxide (d) 125.84 g (5) titanium(IV) oxide (e) 138.9 g (6) manganese(II) chloride (f) 143.1 g (7) phosphine, PH3 (g) 156.7 g (8) tin(II) fluoride (h) 216.6 g (9) lead(II) sulfide (i) 239.3 g (10) copper(I) oxide (j) 331.6 g

Step 1 of 3

Hybridization of Atomic Orbitals Linus Pauling­ 1935 Hybridization (combined) Atomic Orbitals­ different atomic orbitals can combine to give new hybrid orbitals These hybrid orbitals reflect the geometry of the molecule The problem comes from not knowing which molecules hybridize and which ones don’t Predicting Hybridization of Atomic Orbitals Difficult to predict Rules 1. Determine the geometry of the regions of high electron density 2. Assign the set of hybridized orbitals that corresponds to the geometry Sp ­ linear, 180° 2 Sp ­ trigonal, 120° 3 Sp ­ tetrahedral, 109.5° 3 Sp d ­ trigonal bipyramidal, 120°, 90° 3 2 Sp d ­ octahedral, 90° Only three possible hybridization modes for Carbon­ Sp, Sp , Sp2 3 Geometry of Hybridization of Orbitals
