The Shapes of Molecules  Most molecules are 3-Dimensional molecules.  Molecules are found to have certain shapes.  Example;  a pyramid, linear, planar.
1 Shapes of Molecules Determined by number of valence electrons of the central atom 3-D shape a result of bonded pairs and lone pairs of electrons Use.
SHAPES OF MOLECULES. REMINDER ABOUT ELECTRONS  Electrons have negative charges  Negative charges “repel” each other  In molecules, electrons want to.

VSEPR plan Importance of molecular “shapes” CO2 vs SO2 vs H2O Drug molecules / interactions CO2 vs SO2 vs H2O Similarities? Differences? (How to explain these?) Quick answer/run through 5 “Parent” Structures (What “family” are you in?) Importance of how to count electron “groups” (or electron clouds) [not just for VSEPR!] My approach (Family first, then consider lone pairs)
