To Do • 7th Lon-Capa assignment due tomorrow by 10 pm. • Quiz #5 on Wednesday, April 13 in Discussion. • Read Chapter 10.1, 10.2, and 10.8 and do the suggested homework.
VSEPR – General Guidelines • Draw the Lewis structure. • If the octet rule is exceeded, add electrons to the central atom. • Multiple bonds count as one direction (or one “effective pair”). • Consider the lone pairs when determining the geometry. • Consider only the atoms when determining the shape. • Polarity comes from asymmetry.
Clicker Question How many of the following molecules are polar? • I. COS • II. CCl4 • III. XeF4 • IV. SF4 a) 0 b) 1 c) 2 d) 3 e) 4
(a)The Orbitals Used to Form the Bonds in Ethylene (b) The Lewis Structure for Ethylene
Relationship of the Number of Effective Pairs, Their Spatial Arrangement, and the Hybrid Orbital Set Required
